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.

fd109295a1425ca1cb2b69fe34a294b6189542c0 by Laramie Leavitt <lar@google.com>:
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.
