Optimize prefetch codegen.

Currently we use "r" constraint to pass prefetched address.
This forces the compiler to actually put it into a register.
As the result some uses look as:

 16bfb7c: 48 01 cf add %rcx,%rdi
 16bfb7f: 0f 0d 0f prefetchw (%rdi)
--
 16bfccf: 48 83 c1 60 add $0x60,%rcx
 16bfcd3: 0f 0d 09 prefetchw (%rcx)

Use "m" constraint instead. It's more relaxed and requires
to just materialize the address in some form using whatever
addressing modes the target supports (e.g. x86 off(base, index, scale)).
With the change the same code becomes:

 16bfb7c: 0f 0d 0c 39 prefetchw (%rcx,%rdi,1)
--
 16bfccf: 0f 0d 49 60 prefetchw 0x60(%rcx)

Abseil LTS branch, Aug 2023, Patch 1 (#1534)

* Add StdcppWaiter to the end of the list of waiter implementations

Since ABSL_INTERNAL_HAVE_STDCPP_WAITER is defined on all systems
it is effectively a fallback. I left the condition there in case
we have to disable it on some platform in the future.

Switch time_state to explicit default initialization instead of value initialization. (#1261)

It looks to me like the language rules treat these the same for this type, but evidently GCC feels differently.

This only matters under TSAN where SpinLock has a non-trivial destructor, and under C++20 where ABSL_CONST_INIT is implemented (as constinit) by gcc.

Fixes #1253

Adds bounds-checking to the second range of absl container algorithms (#811)

The APIs for the two-range `absl::c_mismatch`, `absl::c_swap_ranges`,
and `absl::c_transform` are misleading as they do not check the bounds
of the second range against the first one.

This commit cleans up ensures that buggy calls are not exploitable;
non-buggy calls are unaffected.

This is consistent with both C++14's two-range `std::` equivalents and
C++20's `std::ranges::` equivalents.
