Add constructor overloads with signature (Mutex*, const Condition&) to MutexLock, ReaderMutexLock, WriterMutexLock, ReleasableMutexLock, MaybeMutexLock.
These overloads call Mutex::LockWhen, Mutex::ReaderLockWhen, Mutex::WriterLockWhen.
Using the guard classes with these new constructors replaces both manual LockWhen/Unlock sequences and the less-efficient, but popular current pattern of "absl::MutexLock lock(&mu); mu.Await(cond);".

Switch clang compiler detection to use to the Bazel supported mechanism
When Abseil launched, we relied on the compiler string "llvm",
which we manually set when we used the automatic crosstool generation
by using the environment variable BAZEL_COMPILER. Today, Bazel detects
clang and automatically sets the compiler string to "clang".

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
assert((absl::btree_map<K, V>::testonly_uses_linear_node_search()));

absl::c_mismatch is based on std::mismatch, which requires that its

absl::c_mismatch using `*first1 != *first2` which assumes that the

This CL reverts that behaviour.

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.

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.
