[libc++] Remove internal "build-with-external-thread-library" configuration
Our threading support layer is currently a huge mess. There are too many
configurations with too many confusing names, and none of them are tested
in the usual CI. Here's a list of names related to these configurations:
LIBCXX_BUILD_EXTERNAL_THREAD_LIBRARY
_LIBCPP_BUILDING_THREAD_LIBRARY_EXTERNAL
LIBCXXABI_BUILD_EXTERNAL_THREAD_LIBRARY
_LIBCPP_HAS_THREAD_LIBRARY_EXTERNAL
LIBCXX_HAS_EXTERNAL_THREAD_API
_LIBCPP_HAS_THREAD_API_EXTERNAL
This patch cleans this up by removing the ability to build libc++ with
an "external" threading library for testing purposes, removing 4 out of
6 "names" above. That setting was meant to be used by libc++ developers,
but we don't use it in-tree and it's not part of our CI.
I know the ability to use an external threading API is used by some folks
out-of-tree, and this patch doesn't change that. This only changes the
way they will have to test their external threading support. After this
patch, the intent would be for them to set `-DLIBCXX_HAS_EXTERNAL_THREAD_API=ON`
when building the library, and to provide their usual `<__external_threading>`
header when they are testing the library. This can be done easily now
that we support custom lit configuration files in test suites.
The motivation for this patch is that our threading support layer is
basically unmaintainable -- anything beyond adding a new "backend" in
the slot designed for it requires incredible attention. The complexity
added by this setting just doesn't pull its weigh considering the
available alternatives.
Concretely, this will also allow future patches to clean up
`<__threading_support>` significantly.

[Flang][OpenMP][MLIR] Filter emitted code depending on declare target and device
This patch adds support for selecting which functions are lowered to LLVM IR
from MLIR depending on declare target information and whether host or device
code is being generated.
The approach proposed by this patch is to perform the filtering in two stages:
- An MLIR transformation pass, which is added to the Flang translation flow
after the `OMPEarlyOutliningPass`. The functions that are kept are those
that match the OpenMP processor (host or device) the compiler invocation
is targeting, according to the presence of the `-fopenmp-is-target-device`
compiler option and declare target information. All functions contaning an
`omp.target` are also kept, regardless of the declare target information of
the function, due to the need for keeping target regions visible for both
host and device compilation.
- A filtering step during translation to LLVM IR, which is peformed for those
functions that were kept because of the presence of a target region inside.
If the targeted OpenMP processor does not match the declare target
information of the function, then it is removed from the LLVM IR after its
contents have been processed and translated. Since they should only contain
an omp.target operation which, in turn, should have been outlined into
another LLVM IR function, the wrapper can be deleted at that point.

[clang] Fix delayed template parsing
Commit
98390ccb80569e8fbb20e6c996b4b8cff87fbec6 fixed late template
instantiation by clearing FP pragma stack before instantiation. This
solution was based on the assumptions:
- FP pragma stack is not used anymore and it is safe to clear it,
- Default FP options are determined by command line options.
Both the assumptions are wrong. When compilation produces precompiled
header file, state of the stack is serialized and then restored when the
precompiled header is used. Delayed template parsing occurs at the end
of translation unit but before serialization, so clearing FP pragma
stack effects serialized representation. When the precompiled file is
loaded, some conditions can be broken and clang crashed, it was
described in https://github.com/llvm/llvm-project/issues/63704. The
crash was observed only in few cases, on most buildbots it was absent.
The violation of expected conditions was caused by violation of the
second assumption. FPEvalMethod can be modified by target, so it is not
possible to deduce it from LangOptions only. So default FP state read
from precompiled header was different from the state in the initialized
Sema, and this was the crash reason.
Only two targets do such modification of default FP options, these are
i386 and AIX. so the problem was hard to reproduce.
Delayed template parsing should occur with empty pragma stack, so it
must be cleared before the instantiation, but the stack now is saved
and restored after the instantiation is done.
This change should fix https://github.com/llvm/llvm-project/issues/63704.

They can be changed by the cmake variable

LLVM has had its own custom CMake flags, e.g. LLVM_USE_CRT_RELEASE,

these and direct users to use CMAKE_MSVC_RUNTIME_LIBRARY directly
instead (and do a best effort attempt at setting CMAKE_MSVC_RUNTIME_LIBRARY

simple cases, it doesn't handle multi-config generators with
different LLVM_USE_CRT_* variables for different configs though,
but that's probably fine - we should move over to the new upstream
CMake mechanism anyway, and push users towards that.
Change code in compiler-rt, that previously tried to override the
CRT choice to /MT, to set CMAKE_MSVC_RUNTIME_LIBRARY instead of
meddling in the old variables.

[mlir][ODS] Add support for passing properties to `ref` in `custom`
This is essentially a follow up to https://reviews.llvm.org/D155072
This adds support for also passing properties as `ref` parameter to `custom`. This requires the property to have been bound previously and will error otherwise. This makes it possible for an implementation of `custom` to take previously parsed data into account, creating nice context-dependent grammars :-)
