Default stack alignment of x86 NaCl to 16 bytes

X86 NaCl generally requires the stack to be aligned to 16 bytes.
This change was already implemented in two downstream NaCl compilers
based on llvm.

[symbolizer] Added StartAddress for the resolved function.

In many cases it is helpful to know at what address the resolved function starts.
This patch adds a new StartAddress member to the DILineInfo structure.

[OpenMP] Stabilize OpenMP/parallel_for_codegen.cpp test (NFC)

Revert recent commit to require x86-registered-target (e4b790c5e3653053819182a67c593bc65de860ac).
Remove -O1 from the run lines so they are less dependent on backend passes.
Update the CHECK6 and CHECK10 lines with script.

[SampleFDO] New hierarchical discriminator for Flow Sensitive SampleFDO

This patch implements first part of Flow Sensitive SampleFDO (FSAFDO).
It has the following changes:
(1) disable current discriminator encoding scheme,
(2) new hierarchical discriminator for FSAFDO.

For this patch, option "-enable-fs-discriminator=true" turns on the new
functionality. Option "-enable-fs-discriminator=false" (the default)
keeps the current SampleFDO behavior. When the fs-discriminator is
enabled, we insert a flag variable, namely, llvm_fs_discriminator, to
the object. This symbol will checked by create_llvm_prof tool, and used
to generate a profile with FS-AFDO discriminators enabled. If this
happens, for an extbinary format profile, create_llvm_prof tool
will add a flag to profile summary section.

[libc++] Some fixes to the <bit> utilities.

Fix __bitop_unsigned_integer and rename to __libcpp_is_unsigned_integer.
There are only five unsigned integer types, so we should just list them out.
Also provide `__libcpp_is_signed_integer`, even though the Standard doesn't
consume that trait anywhere yet.

Notice that `concept uniform_random_bit_generator` is specifically specified
to rely on `concept unsigned_integral` and *not* `__is_unsigned_integer`.
Instantiating `std::ranges::sample` with a type `U` satisfying
`uniform_random_bit_generator` where `unsigned_integral<U::result_type>`
and not `__is_unsigned_integer<U::result_type>` is simply IFNDR.

Orthogonally, fix an undefined behavior in std::countr_zero(__uint128_t).

Orthogonally, improve tests for the <bit> manipulation functions.
It was these new tests that detected the bug in countr_zero.
