Changes

[SLP]Fix PR55796: insert point for extractelements from different basic blocks.

Extractelement instructions may come from different basic blocks, need
to take it into account when looking for a last instruction in the
bundle to prevent compiler crash.

compiler-rt: Allow build without __c11_atomic_fetch_nand

Don't build atomic fetch nand libcall functions when the required
compiler builtin isn't available. Without this compiler-rt can't be
built with LLVM 13 or earlier.

Not building the libcall functions isn't optimal, but aligns with the
usecase in FreeBSD where compiler-rt from LLVM 14 is built with an LLVM
13 clang and no LLVM 14 clang is built.

[mlir][python][ctypes] fix ctype python binding complication for complex

There is no direct ctypes for MLIR's complex (and thus np.complex128
and np.complex64) yet, causing the mlir python binding methods for
memrefs to crash. This revision fixes this by passing complex arrays
as tuples of floats, correcting at the boundaries for the proper view.

NOTE: some of these changes (4 -> 2) were forced by the new "linting"

sanitizers: Do not include crypt.h if SANITIZER_INTERCEPT_CRYPT_R is undef

sanitizer_intercept_overriders.h might override SANITIZER_INTERCEPT_CRYPT_R to
be undefined. There's no need to require crypt.h in that case.

(The motivation is that crypt() moved from glibc into its own package at some
point, which makes intercepting it and building with a single sysroot that
supports both pre-bullseye and post-bullseye a bit hairy.)

ar_to_bc.sh: Ignore non-bitcode files in archives

The script uses llvm-link to link LLVM bitcode files.
5426da8ffa4a6d55adab21026ce6ebe8f1cc6ef2 used -DLLVM_DISABLE_ASSEMBLY_FILES=ON
to ignore object files compiled from lib/Support/BLAKE3/*.S.

A better approach (which fits Bazel better) is to ignore non-bitcode files.

[Libomptarget] Add basic support for dynamic shared memory on AMDGPU

This patchs adds the arguments necessary to allocate the size of the
dynamic shared memory via the `LIBOMPTARGET_SHARED_MEMORY_SIZE`
environment variable. This patch only allocates the memory, AMDGPU has a
limitation that shared memory can only be accessed from the kernel
directly. So this will currently only work with optimizations to inline
the accessor function.

[libc] Keep all thread state information separate from the thread structure.

The state is now stored on the thread's stack memory. This enables

Fix an incorrect bit-width for storing attribute syntax information

This field corresponds to the Syntax enumeration, and that gained
another entry in 1fdf952deeb9a02aa34794af3c1a7d13a30e068e. However,
the bit-field for storing the syntax used was not adjusted to handle
the extra field.

This turns out to be unobservable for HLSL attributes at the moment, so
there is no test coverage. But it's also not really an NFC change
either.

This reduces the time emitStabs() takes by about 275ms, or 3% of overall

This reverts commit a544710cd43ba9f7729a613c58729f146e792a8e.

See discussion in D120540.

This breaks C++ Clang modules on Darwin and also more than a dozen
tests in the LLDB testsuite.  I think we need to be more careful to
separate out the enabling of Clang C++ modules and C++20
modules. Either by having -fmodules-ts control the HaveModules flag,
or by adding a way to explicitly turn them off.

Keeps MVT::i2, MVT::i4 lowering actions as `expand`, which should be
removed once targets set this explicitly.
