Single characters are more efficient to search for. Extending this API allows

Reduced latency and code-size of some InlinedVector methods:
1. Simpler fast path for push_back/emplace_back.
2. Do not inline slow path of push-back/emplace_back.
3. Simplify resize implementation.
Performance:
A simple benchmark that does the following per iteration:
```
push_back on an InlinedVector<int64>
push_back on an InlinedVector<bool>
```
Sees iteration time go from 4.3ns to 2.8ns and code size shrink from 1129 bytes to 175 bytes.

Simplify unaligned memory access functions.
The #ifdef to produce calls to __sanitizer_unaligned_load16 etc were needed in past versions of this code, when we were lying to the compiler about the alignment of the loads/stores, by using a reinterpret_cast.
However, a year ago, absl switched to simply use memcpy. Sanitizers support this correctly by default, nothing extra is required.

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
|| 0x
m > capacity_ 1x
overall branches 3x
(GrowthToLowerboundCapacity 1x, NormalizeCapacity 1x, reserve 1x)

Improve cache-locality for ThreadIdentity and PerThreadSynch.
This is a change based on an observation in RPC benchmarks that shows
significant cycles being spent in waking up a thread, 99.8% of which
was on cache misses. Investigating this a bit more, it turns out to
be due to sharing the cache line with the waiter state.
To fix this issue, the following changes are introduced:
- Reorder fields in PerThreadSync so that it fits in a single cache line
The size of this structure was 80 bytes before this change.
Note: Manually inspected all booleans to make sure they are not modified by
multiple threads concurrently.

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

Improve performance of the registry:
- Reduce contention
- Reduce memory usage for each flag by `6*sizeof(void*)`.
- Replace one immortal allocation per-flag with a single one for all the flags
- Slightly improve single-threaded performance by avoiding the std::map indirections.

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.

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
versions of both GCC and LLVM. Since the LLVM build targets Debian 10,
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.
This also includes fixes to get the build working with the
new toolchains.

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.

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.
