internal/stacktrace_x86-inl.inc includes internal/raw_logging.h and therefore needs
a direct dependency to satisfy Bazel layering_check (Clang -fmodules-strict-decluse).
Clang before https://reviews.llvm.org/D132779 does not report the issue becasue:
* internal/stacktrace_x86-inl.inc is an .inc file and is not checked as a main file
* internal/stacktrace_x86-inl.inc is a textual header and older Clang incorrectly
considers there is no requesting module and suppresses the error.

Many improvements to LeakChecker builds
The presence of the LeakChecker is now detected when possible. GCC
users using LeakChecker in standalone mode still need to use
-DLEAK_CHECKER. This is now documented in the header.
The hacky targets used for testing leak checking have been removed in
favor of testing in AddressSanitizer mode on Kokoro.

Alternative bit mixer for LowLevelHash on ARM
LowLevelHash's bit-mixer is inefficient on ARM because it calculates a 128-bit product of two 64-bit numbers. On ARM, this requires a sequence of two instructions with a high combined latency and poor throughput. This change provides alternative bit-mixing code for ARM that uses only 64-bit arithmetic (multiplication, xor, and left-shifts) and speeds things up considerably.
The bit-mixing code for ARM was inspired by by Woothash[1] and xxh3[1]. Once I landed on a sequence of operations that provided good mixing, I used a test harness to search for the combination of shift / rotate factors that provided the best mixing, as indicated by SMHasher hash quality tests. The new mixing code passes 13 out of 15 of the hash quality test suites in SMHasher, with the two failures being in the noise range: e.g. 1 collision vs. zero expected in a keyset of ~8m keys.

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That has been replaced by type-erasure which looks for a method named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.

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.
