Correct WEAK attribute enabling condition.
ABSL_ATTRIBUTE_WEAK is present if:
compiler has built-in attribute weak
OR
we are using gcc (and not clang)
AND
we are not on windows
OR
we use windows clang version >= 9.0.0
AND
we are not on MinGW

There are magic numbers in the expected load factors and probe lengths, and they seem to be wrong especially under msvc. Even under the linux tool chain, these tests fail occasionally. Fix the magic numbers to make the tests succeed.

Manually align buffers in randen_engine.
In C++ it's implementation defined whether types with extended alignment are supported.
randen_engine uses vector intrinsics with 16-byte alignment requirements in
some instances, so internally we allocate an extra 8 bytes to manually align to 16.
No detectable performance impact.

Fix float conversion for PPC.
In PPC `long double` is a double-double representation which behaves weirdly
wrt numeric_limits. Don't take `long double` into account when we are not
handling `long double` natively anyway.
Fix the convert test to always run the conversion even if we are not going to
compare against libc's printf result. This allows exercising the code itself to
make sure we don't trigger assertions or UB found by sanitizers.

Remove endian-sensitivity from Abseil’s RNG
Ensure that the Abseil random number generator produces identical output
on both big- and little-endian platforms by byte-swapping appropriately
on big-endian systems.

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.
