This allows symbolization to work if different parts of a binary's text are mapped differently, e.g. if they're mlock()ed or mapped onto huge pages.

This ensures that emmintrin.h is included with clang-cl. Otherwise, errors like
this occur:
.../absl/container/internal/raw_hash_set.h(536,8): error: unknown type name '__m128i'
inline __m128i _mm_cmpgt_epi8_fixed(__m128i a, __m128i b) {
This aligns the include ifdef guards and the guards that use the provided APIs.
The includes are also reordered, so they appear after the config header which
provides the internal macro values.

As part of this update, GoogleTest is now using the Abseil flags
implementation, and the flags usage_test needs to be modified to pass.
If building with bazel and --define=absl=1 to force GoogleTest to use
Abseil, a WORKSPACE dependency on the abseil branch of the RE2 project
is now required.

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.

When we would perform a stacktrace using the frame pointer walking, because we
did the adjustment for the return address separately, we were misaligning the
stack size and frame. Simplify the logic and correct the offset.
The recovered frame pointer provides us with the return address of the current
frame and the previous frame's frame pointer. Subsequently, we decide if we
want to record this frame or not. The value in `next_frame_pointer` already
points to the value from the previous stack frame (that is the next frame
pointer to iterate). As such, the value computed by `ComputeStackFrameSize` is
the value for the current frame. This was offset by one previously.
Take the opportunity to clean up some of the local comments, fixing typos and
splitting up the comments to reflect the lines that they are associated with.

A few targets were missing `linkopts = ...` and so were not obeying
the project-wide default settings.
Omit any changes to cctz for now, because it's vendored from another project.
For portability, absl_time_test builds a small, incomplete tzdata
database into the test binary and uses that instead of the system tzdata
database. (absl_time_test needs to run on some platforms that lack a
system tzdata database.) However, this causes issues if TZ is set to
something that isn’t in the test database. To address them, fall back to
America/Los_Angeles if TZ is set to an unknown value during testing.

The key idea is to avoid using 16 byte NEON and use 8 byte NEON which has lower latency for BitMask::Match. Even though 16 byte NEON achieves higher throughput, in SwissMap it's very important to catch these Matches with low latency as probing on average happens at most once.
I also introduced NonIterableMask as ARM has really great cbnz instructions and additional AND on scalar mask had 1 extra latency cycle

The "deleted" overload error is useless to users. By passing some dummy string to the base class constructor we use a valid constructor and remove the unintended use of the deleted default constructor.

Decompose RandenPoolSeedSeq from NonsecureURBGBase.
Adjust how the RandenPoolSeedSeq detects contiguous buffers passed to the generate function. Previously it made incorrect assumptions regarding the contiguous concept, which have been replaced with some type-based tests for a small number of known contiguous random access iterator types, including raw pointers.

We were using `init_type`s for temp values that we would move into slots, but in this case, we need to have actual slots. We use node handles for managing slots outside of nodes.
Also, in btree::copy_or_move_values_in_order, pass the slots from the iterators rather than references to values. This allows for moving from map keys instead of copying for standard layout types.
In the test, fix a couple of ClangTidy warnings from missing includes and calling `new` instead of `make_unique`.

the Unlock path now uses an atomic exchange, so the missed wakeup
