Summary:
The linker wrapper uses this metadata to determine which registration
code to emit, e.g. CUDA, HIP or OpenMP. If we encounter an OFK_None we
should just ignore it.

On AIX, profiled system libraries are stored at `/lib/profiled` and
`/usr/lib/profiled`. When compiling with `-pg`, we want to link against
libraries in those directories. This PR modifies the AIX toolchain to
add those directories to the linker search paths.

A follow-up to D136133. It was mentioned in #58382 that there is a need
to test for DRs that have not been officially resolved yet. This patch
aims to replace original "hackery" with proper handling for such cases.
Highlights:

- Availability can be suffixed (further) with "open", "drafting", or
  "review", e.g. // dr2565: 16 open, // drXXXX: 16 c++17 drafting
- Checks are implemented to ensure that this suffix corresponds to
  actual issue status
- Non-resolved DRs are counted (stdout of make_cxx_dr_status)
- No changes made to cxx_dr_status.html
- 'c++20' availability suffix added
- Remove 'concurrency' status since it's no longer
  on the list of statuses in CWG Active Issues

This extension only adds builtin functions and thus doesn't need to be
included as an extension.  Instead of a pragma, the builtin functions
of the extension can be exposed through enabling preprocessor defines.

This reverts commit 18244321.

This change is focussed on simplifying `Support/Host.h` to only do
target detection. In this case, this function is close in usage to
existing functions in `Support/Threading.h`, so I moved it into there.
The function is also renamed to `llvm::get_physical_cores()` to match
the style of threading's functions.

The big change here is that now if you have threading disabled,
`llvm::get_physical_cores()` will return -1, as if it had not been able
to work out the right info. This is due to how Threading.cpp includes
OS-specific code/headers. This seems ok, as if threading is disabled,
LLVM should not need to know the number of physical cores.

As strange as it seems to our files-are-strings view of the world, some editors
that treat files as arrays of lines can get confused about whether the last line
has a newline or not.

The consequences of failing to handle a bad incremental update are catastrophic.
If an update would be valid except for a missing newline at end of file, pretend
one exists.

Some headers in LLDB work only when considered as textual inclusion, but not if one attempts to use them on their own or with a different context.

- python-typemaps.h: uses Python definitions without using "Python.h".
- RISCVCInstructions.h uses RISC-V register enums without including the enums header.
- RISCVInstructions.h includes EmulateInstructionRISCV.h, but is unnecessary since we forward-declare EmulateInstructionRISCV anyway. Including the header is problematic because EmulateInstructionRISCV.h uses DecodeResult which isn't defined until later in RISCVInstructions.h.

This makes LLDB build cleanly with the "parse_headers" feature [1]. I'm not sure what the analagous CMake option is.
