Ignore missing CPU frequency on more architectures
Linux on MIPS, PA-RISC, RISC-V, and SystemZ doesn’t expose the nominal
CPU frequency via /sys, so don’t worry if `NominalCPUFrequency` returns
1.0 on those platforms.
Some POWER machines expose the CPU frequency; others do not. Since we
can’t predict which type of machine the tests will run on, simply
disable testing for `NominalCPUFrequency` on POWER.

Add flag for 'shallow subcord' feature for experimental ring buffer rollout
There is a potential trade-off of CPU cost vs over-sharing cord data for subcord of large cords. This flag allows making subcords shallow for ringbuffers (with a potential larger waste of referenced source cords), which allows us to make subcord fast for this apps that do no persist (unmodified / plain copied) sub cords.
This change also introduces constants for the default settings, intended to keep the internal cord settings concistent with external flags.

Move CordRep Ref() and Unref() logic into cord_internal.h
This change moves Ref() and Unref() logic out of cord.cc into cord_internal. The main purpose is to make upcoming ring buffer changes easier to isolate from existing cord.cc code. Notice that this removes the nullptr check from Unref() and now requires it to be non null (which held true most times). We may need to rethink if the 'unref unlikely one' is the common case: are cordreps most likely shared? This may be something between 'root' and non root nodes, i.e., is it more likely for leaf / flat nodes in large cords to be shared than top level cordreps being shared? Vice versa? Benchmarks say that we mostly shouldn't care, the caveat being that atomic ops seem more expensive on upcoming archs (arcadia) so we should error on the side of an extra IsOne() branch saving us single owned atomic ops.

Extract `find_first_not_full` outside of the raw_hash_set.
This function is used in the following scenarios:
0. [relatively hot] insert, when actual new element is added.
1. [relatively cold] resize (explicit or on capacity grow)
2. [relatively cold] copy constructor
3. [cold] rehash on insert/erase (aka cache) use cases
Resize typically mitigated by `reserve` in performance critical cases. Rehashing happen relatively rare, when hash table become polluted with deleted slots.
We keep `find_first_not_full` in header, so that compiler still can inline it, when necessary (most notably in insert use case).
This reduce binary size since only one copy of this function will be present in the binary for all tables where the function is not inlined (at least in one case).

Implement `reserve` more explicit to avoid calling `rehash`.
`reserve` is much more widely used method and doesn't need extra logic present in `rehash`.
E. g., accidental `t.reserve(0)` on non empty table shouldn't cause rehashing, which was a case before this change.
It also remove some unnecessary computations from `reserve`.
Was:
```
GrowthToLowerboundCapacity 2x
NormalizeCapacity 1x
bitwise | 1x
n == 0 && capacity_ == 0 1x
n == 0 && size_ == 0 1x
n == 0 1x
|| 1x
m > capacity_ 1x
overall branches 6x
(GrowthToLowerboundCapacity 2x, NormalizeCapacity 1x, rehash 3x)
```
Now:
```
GrowthToLowerboundCapacity 1x
NormalizeCapacity 1x
bitwise | 0x
n == 0 && capacity_ == 0 0x
n == 0 && size_ == 0 0x
n == 0 0x

da5e09a7fedb3217329465d9206b7cbc6677176b by Abseil Team <absl-team@google.com>:
Add `absl_btree_prefer_linear_node_search`
Allow keys of `btree_set`, `btree_map`, `btree_multiset`, and `btree_multimap`
to opt-in to linear search (instead of binary search). Linear search was
used previously for arithmetic types with `key_compare` of `std::greater`
or `std::less`.
For example, this would be useful for key types that wrap an integer
and define their own cheap `operator<()`.
```
class K {
public:
using absl_btree_prefer_linear_node_search = std::true_type;
...
private:
friend bool operator<(K a, K b) { return a.k_ < b.k_; }
int k_;
};
absl::btree_map<K, V> m; // Uses linear search
assert((absl::btree_map<K, V>::testonly_uses_linear_node_search()));
```

changes how non-equality is evaluated
absl::c_mismatch is based on std::mismatch, which requires that its
iterators' reference types meet the requirements of
Cpp17EqualityComparable[1]. The previous CL mistakenly wrote
absl::c_mismatch using `*first1 != *first2` which assumes that the
reference types model std::equality_comparable[2] (which was only added
in C++20).
This CL reverts that behaviour.

On macOS, `mem_alloc` is defined like this:
rpc/types.h:86:#define mem_alloc(bsize) calloc(1, bsize)
So if that file is included before container_memory.h, the variable mem_alloc
may never get defined. This is fixed by using a different name.

Provide mutable access to the key in node handles using std::launder when compiled with C++17 or later.
Also, document why we can't provide mutable access to the key without C++17.
Note: we use Policy::mutable_key() because btree already uses Policy::key() internally to get const key access, and we want to avoid calling std::launder unless we need mutable access to the key.

Avoid a costly divide (the division accounts for 10% of the time spent in the function).
When the division is signed, the compiler has to generate a div. When it is unsigned, it can generate a shift: https://godbolt.org/z/vGfTv4. As per the test above the div, we know that the value is unsigned.

We no longer need the API requirement that alignof(Releaser) <= (default `::operator new` alignment).
Also remove another static_assert from a TODO in cord_internal.h and fix some warnings about calling std::move on a forwarding reference.

Code simplification: consolidate methods to erase values/nodes.
Motivation: this will make floating storage work simpler.
- Delete erase_same_node/erase_from_leaf_node/remove_value/remove_values_ignore_children.
- Move node deletion methods inside btree_node.
- Delete three-argument move() and use transfer_n() instead.
- Note: there's still one usage of move (in btree::erase(iterator)) that could use transfer, but I think doing so would add more complexity than it's worth.

This create a new "hybrid" docker image that includes the latest

but Debian 10 uses an older version of libstdc++ that doesn't have
full C++20 support, the easiest solution is to use the GCC/Debian 10
base image from DockerHub and copy LLVM into it.

Improve FastUniformBits performance for std::minstd_rand.
The rejection algorithm was too pessimistic before, and not in line with the [rand.adapt.ibits]. Specifically, when sampling from an URBG with a non power of 2 range, FastUniformBits constructed a rejection threshold with a power-of-2 range that was too restrictive.
For example, minstd_rand has a range of
[1, 2147483646], which has a range of 2145386495, or about 30.999 bits.
Before FastUniformBits rejected values between 1<<30 and 2145386495, which includes approximately 50% of the generated values. However, since a minimum of 3 calls are required to generate a full 64-bit value from an entropy pool of 30.9 bits, the correct value for rejection sampling is the range value which masks 21 (0x7fe00000) or 22 bits and rejects values greater than that. This reduces the probability of rejecting a sample to about 0.1%
NOTE: Abseil random does not guarantee sequence stability over time, and this is expected to change sequences in some cases.

Small fix to previous change: the first overload of insert_iterator_unique wasn't actually being selected. Fix that issue and add tests to verify that it actually works.
Note: couldn't use TestInstanceTracker here because that counts instances (and decrements in destructor) rather than counting all constructor calls.

Add a hint message to the assertions for easier debugging.
Also, move it out of the template to avoid printing the whole template
instantiation as part of the assertion. It is not relevant and can
significantly bloat the error message and hide the important bits.

Remove the MockingBitGenBase base class in favor of type-erasure in BitGenRef.
In Abseil random, mocking was split across two different classes,
MockingBitGenBase and MockingBitGen. This split existed because Google Mock is a
test-only library that we don't link into production, so MockingBitGenBase
provided a low-overhead scaffold used to lookup mocks when in test code, but
which is unused in production code.
That has been replaced by type-erasure which looks for a method named
CallImpl with the correct signature.
Weaken the coupling between MockingBitGen, DistributionCaller, and MockOverloadSet.
Rename CallImpl to InvokeMock()
Previously, the implementation of DistributionCaller was also split across different files using explicit instantiation of the DistributionCaller struct and some details in the Mocking classes. Now Distribution caller uses the presence of the InvokeMock() method to choose whether to use the mockable call path or the default call path.

Slight restructuring of absl/random/internal randen implementation.
Convert round-keys.inc into randen_round_keys.cc file.
Consistently use a 128-bit pointer type for internal method parameters. This allows simpler pointer arithmetic in C++ & permits removal of some constants and casts.
Remove some redundancy in comments & constexpr variables. Specifically, all references to Randen algorithm parameters use RandenTraits; duplication in RandenSlow removed.

Change many distribution tests to use pcg_engine as a deterministic source of entropy.
It's reasonable to test that the BitGen itself has good entropy, however when testing the cross product of all random distributions x all the architecture variations x all submitted changes results in a large number of tests. In order to account for these failures while still using good entropy requires that our allowed sigma need to account for all of these independent tests.
Our current sigma values are too restrictive, and we see a lot of failures, so we have to either relax the sigma values or convert some of the statistical tests to use deterministic values.
This changelist does the latter.
