Query the executable for address size.

These names are never used so just waste a lot of memory. If do need
them ever, it would be better to store pointers to the StringMapEntry
objects that store the same strings.

Pull Request: https://github.com/llvm/llvm-project/pull/74896

An 8 bit bitfield should not have a preferred type of bool.

This fixes a clang-tidy diagnostic when building libc++ with RTTI
disabled. This was originally part of #65518.

Fixes regression introduced in b3e6ff33
Fixes bot failure https://lab.llvm.org/buildbot/#/builders/60/builds/15037

This adds the std.compat module. The patch contains a bit of refactoring
to avoid code duplication between the std and std.compat module.

Implements parts of
- P2465R3 Standard Library Modules std and std.compat

This change requires quite a number of changes in the tests; this is not
code I expect people to use in the wild. So I don't expect breakage for
users.

Implements:
- P2905R2 Runtime format strings, as a Defect Report

This commit introduces support for the MSVC-specific C++11-style
attribute `[[msvc::constexpr]]`, which was introduced in MSVC 14.33.
The semantics of this attribute are enabled only under
MSVC compatibility (`-fms-compatibility-version`) 14.33 and higher.
Additionally, the default value of `_MSC_VER` has been raised to 1433.

The current implementation lacks support for:
- `[[msvc::constexpr]]` constructors (see #72149);
  at the time of this implementation, such support would have required
  an unreasonable number of changes in Clang.
- `[[msvc::constexpr]] return ::new` (constexpr placement new) from
  non-std namespaces (see #74924).

Relevant to: #57696

This patch continues the work started with ea5b1ef0. See that commit and its
corresponding PR for details.

Invert the logic and choose the ELF path by default as a fallback. Move
check for Darwin to the top.

These both do the same thing, but some profiling on a
Releast+Asserts build suggests isRVVSizelessBuiltinType() is the
more efficient version so lets keep that one.

MachOPlatformRuntimeState::lookupSymbols encapsulates the approach used in
dlsym in bb41fc68, but generalizes it to multiple symbols:
  1. try to resolve symbols locally
  2. issue a push-request for any unresolved symbols
  3. re-try local resolution

In the future lookupSymbols can serve as the basis for a public bulk lookup
API in the ORC runtime.

AFAICT, `ModuleFile::File` can be `std::nullopt` only for PCM files
loaded from the standard input. This patch starts setting that variable
to `FileManager::getSTDIN()` in that case, which makes it possible to
remove the optionality, and also simplifies code that actually reads the
file.

This is part of an effort to get rid of
`Optional{File,Directory}EntryRefDegradesTo{File,Directory}EntryPtr`.

[Flang][OpenMP][Semantics] Modify errors to warnings for semantic checks in IS_DEVICE_PTR related to list-items being dummy arguments. (#74370)

Changed semantic check from giving error to giving a warning about
deprecation from OpenMP 5.2 and later about checks for dummy argument
list-items present on IS_DEVICE_PTR clause.

Reapply llvm/llvm-project#72713 after fixing formatted printing of
`uint64_t` values as hex (see failing build here
https://lab.llvm.org/buildbot/#/builders/186/builds/13604).

This patch adds llvm-readobj support for:

- Dynamic `R_AARCH64_AUTH_*` relocations (including RELR compressed AUTH
relocations) as described here:

- `.note.AARCH64-PAUTH-ABI-tag` section as defined here
https://github.com/ARM-software/abi-aa/blob/main/pauthabielf64/pauthabielf64.rst#elf-marking

This reverts the following commits:
