Shilei Tian 7be3285248 [OpenMP] Not set OPENMP_STANDALONE_BUILD=ON when building OpenMP along with LLVM
For now, `*_STANDALONE_BUILD` is set to ON even if they're built along
with LLVM because of issues mentioned in the comments. This can cause some issues.
For example, if we build OpenMP along with LLVM, we'd like to copy those OpenMP
headers to `<prefix>/lib/clang/<version>/include` such that `clang` can find
those headers without using `-I <prefix>/include` because those headers will be
copied to `<prefix>/include` if it is built standalone.

In this patch, we fixed the dependence issue in OpenMP such that it can be built
correctly even with `OPENMP_STANDALONE_BUILD=OFF`. The issue is in the call to
`add_lit_testsuite`, where `clang` and `clang-resource-headers` are passed as
`DEPENDS`. Since we're building OpenMP along with LLVM, `clang` is set by CMake
to be the C/C++ compiler, therefore these two dependences are no longer needed,
where caused the dependence issue.

Jonas Hahnfeld 0e0483bf5c [OpenMP][CMake] Fix version detection of testing compiler

and LLVM_VERSION_MINOR. This has been wrong since the code was added

Joel E. Denny ba942610f6 [OpenMP] Add scaffolding for negative runtime tests
Without this patch, the openmp project's test suites do not appear to
have support for negative tests.  However, D78170 needs to add a test
that an expected runtime failure occurs.

This patch makes `not` visible in all of the openmp project's test
suites.  In all but `libomptarget/test`, it should be possible for a
test author to insert `not` before a use of the lit substitution for
running a test program.  In `libomptarget/test`, that substitution is
target-specific, and its value is `echo` when the target is not
available.  In that case, inserting `not` before a lit substitution
would expect an `echo` fail, so this patch instead defines a separate
lit substitution for expected runtime fails.

Joachim Protze 84637408f2 [OpenMP][Tool] Make tests for archer dependent on TSan
If the openmp project is built standalone, the test compiler is feature tested for an available -fsanitize=thread flag.
If the openmp project is built as part of llvm, the target tsan is needed to test archer.

An additional line (requires tsan) was introduced to the tests, this patch updates the line numbers for the race.

Dimitry Andric 956168c802 Ensure correct pthread flags and libraries are used
On most platforms, certain compiler and linker flags have to be passed
when using pthreads, otherwise linking against libomp.so might fail with
undefined references to several pthread functions.

Use CMake's `find_package(Threads)` to determine these for standalone
builds, or take them (and optionally modify them) from the top-level
LLVM cmake files.

Also, On FreeBSD, ensure that libomp.so is linked against libm.so,
similar to NetBSD.

Adjust test cases with hardcoded `-lpthread` flag to use the common
build flags, which should now have the required pthread flags.

Shoaib Meenai 5be71faf4b [build] Rename clang-headers to clang-resource-headers
Summary:
The current install-clang-headers target installs clang's resource
directory headers. This is different from the install-llvm-headers
target, which installs LLVM's API headers. We want to introduce the
corresponding target to clang, and the natural name for that new target
would be install-clang-headers. Rename the existing target to
install-clang-resource-headers to free up the install-clang-headers name
for the new target, following the discussion on cfe-dev [1].

I didn't find any bots on zorg referencing install-clang-headers. I'll
send out another PSA to cfe-dev to accompany this rename.

This patch also introduces testing for libomptarget-nvptx
which has been missing until now. I propose to add tests for
all bugs that are fixed in the future.
The target check-libomptarget-nvptx is not run by default because
 - we can't determine if there is a GPU plugged into the system.
 - it will require the latest Clang compiler. Keeping compatibility
   with older releases would prevent testing newer code generation
   developed in trunk.

Reasons for expected failures are mainly bugs when using lables in OpenMP regions

For some worksharing clauses, support to distinguish the kind of workshare was

If an issue was fixed in a minor release version of a compiler, we flag the
test as unsupported for this compiler version to avoid false positives.
Same for fixes that where backported to older compiler versions.
