This change introduces the symbol
ABSL_INTERNAL_NEED_REDUNDANT_CONSTEXPR_DECL
to guard redundant declarations of static constexpr data
members that are needed prior to C++17.
This change also introduces the symbol
ABSL_INTERNAL_CPLUSPLUS_LANG, which is supposed to be set
to the same value as __cplusplus, except it uses _MSVC_LANG
on MSVC so that the value is correct on MSVC.
Neither of these new symbols should be used outside of Abseil.

ARM64EC is a Microsoft-designed ARM64 ABI compatible with AMD64
applications on ARM64 Windows 11. The ARM64EC does not support
_umul128 and __rdtsc as x64 intrinsics, though it provides inline
function implementations for them, by emulation. Since the code
already has portable code paths without using the intrinsics,
instead of using the emulated intrinsic implementations, we use
the said portable code paths for ARM64EC.

Revise documentation of bit_cast:
* Removes inappropriate examples (round-tripping pointers, serialization), for which reinterpret_cast is more appropriate.
* Removes mention of "bit representation", which is not an explicit notion in C++. The best we get is "byte representation".
* Removes a circular defition of "bitcast" as itself, and instead explains what it does.
* Removes the mathism "for some values of", which is probably not totally accessible to a general audience, and in any case needless verbiage.
* Fixes comments in the example.
* Replaces some colloquialisms with simpler, more direct language.

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.

s/round/rint/ in exponential_biased
`rint` differs from `round` in that it uses the current FPU rounding
mode. It’s thus potentially faster, since it doesn’t have to save and
restore FPU state. It also is more reflective of developer intent –
most developers expect all FPU operations to use the current rounding
mode, and having exponential_biased follow that rule seems ideal.

This benchmark has significantly different possible behaviors that can result in misleading metrics. Specifically, we can have a case where we are deallocating the last node in the b-tree in the erase and then allocating a new node in the insert call repeatedly, whereas normally, we end up just inserting/erasing a value from the last node. Also, the name of the benchmark is misleading because it involves an erase and an insert, but the name only mentions the insert.

Stop testing with double-double random variables
On POWER, long double is often represented as a pair of doubles added
together (double-double arithmetic). We’ve already special-cased
double-double arithmetic in a number of tests, but compiler
bugs [1, 2, 3] have now triggered both false positives and false
negatives, which suggests testing with double doubles is unlikely to
yield useful signal. Remove the special casing and detect if we’re on a
double-double system; if so, just don’t test long doubles.

Mark popcount helpers as inline.
These are conditionally constexpr, so we need to add inline to cover the
non-constexpr builds to avoid ODR violations.

Use explicit narrowing cast.
This is never invoked in practice, but compilers with -Wimplicit-int-conversion
may trigger when sizeof(T) > sizeof(uint16_t) prior to determining this never
runs.

Ignore missing CPU frequency on more architectures
Linux on MIPS, PA-RISC, RISC-V, and SystemZ doesn’t expose the nominal
CPU frequency via /sys, so don’t worry if `NominalCPUFrequency` returns
1.0 on those platforms.
Some POWER machines expose the CPU frequency; others do not. Since we
can’t predict which type of machine the tests will run on, simply
disable testing for `NominalCPUFrequency` on POWER.

Add flag for 'shallow subcord' feature for experimental ring buffer rollout
There is a potential trade-off of CPU cost vs over-sharing cord data for subcord of large cords. This flag allows making subcords shallow for ringbuffers (with a potential larger waste of referenced source cords), which allows us to make subcord fast for this apps that do no persist (unmodified / plain copied) sub cords.
This change also introduces constants for the default settings, intended to keep the internal cord settings concistent with external flags.

On macOS, `mem_alloc` is defined like this:
rpc/types.h:86:#define mem_alloc(bsize) calloc(1, bsize)
So if that file is included before container_memory.h, the variable mem_alloc
may never get defined. This is fixed by using a different name.

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.
