Skip floating-point edge-case tests when using an x87
32-bit Intel CPUs use 80-bit floats for intermediate values, which can
change the results of floating point computations from what we normally
expect. Identify tests that are sensitive to the x87, and skip them when
we’re on 32-bit Intel.

Mark btree_container::clear() with the ABSL_ATTRIBUTE_REINITIALIZES attribute.
This prevents false positives in the clang-tidy check bugprone-use-after-move;
it allows clear() to be called on a moved-from btree_container without any
warnings, and the btree_container will thereafter be regarded as initialized again.

Round floats using round(x), not static_cast<int>(x + 0.5)
Adding 0.5 to an IEEE float may cause one bit of precision loss, which
is enough to change the result in certain cases. For example,
static_cast<int>(std::round(0.49999999999999994)) == 0
static_cast<int>(0.49999999999999994 + 0.5) == 1

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.
