"win32" is never defined as a lit feature, AFAICT, and Windows bots
appear to be running this just fine.

Part of the project to eliminate special handling for triples in lit expressions.

SED differs between GNU and BSD in handling semicolon and the use of
'\n' in regex patterns. For macOS we can't use these GNU extensions.

The implementation follows the patterns established by the lowering of other
similar intrinsics.

In addition to the code for lowering, the DoTotalReduction template had to be
fixed to correctly break when signaled to do so by the accumulator function.

This patch makes SWIG itself an auto-detected dependency. This allows us
to look for SWIG once in a centralized place and makes it easier
downstream to detect whether to use the static bindings.

This reverts commit a1255dc4.

This patch results in:

  llvm/lib/CodeGen/SanitizerBinaryMetadata.cpp:57:17: error: no member
  named 'size' in 'llvm::MDTuple'

This addresses the issue found by:
https://lab.llvm.org/buildbot/#/builders/92/builds/36372

Take the type from the alloca, not the type to use for allocas.

Fixes issue 59250.

This was assuming a direct reference to the global variable. The
constant string is placed in addrspace 4, and has a constexpr
addrspacecast to the generic address space.

Currently per-function metadata consists of:
(start-pc, size, features)

This adds a new UAR feature and if it's set an additional element:
(start-pc, size, features, stack-args-size)

I had reverted this before the holiday week because a problem was reported with a related change (D137140 - scalable vector known bits in DAG).  I had initially confused the two patches, and then decided to leave this reverted out an abundance of caution.  Now that we're through the holiday week, reapplying.

I also roled in fixes for several post commit review comments that hadn't landed with the original change.

Original commit message

This is a continuation of the series of patches adding lane wise support for scalable vectors in various knownbit-esq routines.

The basic idea here is that we track a single lane for scalable vectors which corresponds to an unknown number of lanes at runtime. This is enough for us to perform lane wise reasoning on many arithmetic operations.

Also fix constructing sanitizer constructors in address space 0 so

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.
