When buildbots are crowded, the libomp LIT tests may hit timeouts so
extend the limit from 1800 to 3000 seconds.

This effectively reverts commit
9ff0cc7e0fa7e99163610d2fcb58e96f3315e343. For some reason "git revert"
lead to "no changes" after fixing conflicts, so a clean revert was not
possible.
The original issue (#57022) is no longer reproducible even with this
patch, so we can remove the suppression.
This is in line with our goal to make -Wenum-constexpr-conversion a
non-downgradeable error, see #59036.

This was added in 4b7beab4187ab0766c3d7b272511d5751431a8da. When the
flag was added implicitly elsewhere, it was added via
llvm/cmake/modules/HandleLLVMOptions.cmake, where it wasn't added on
Windows/Cygwin targets.
This avoids one warning per object file in OpenMP.

When running the tests, we try to invoke them as
"${Python3_EXECUTABLE} ${OPENMP_LLVM_LIT_EXECUTABLE}", but when running
"find_package(Python3)" within the function
"find_standalone_test_dependencies", the variable "Python3_EXECUTABLE"
only gets set within the function scope.
Tests have worked regardless of this in many cases, where executing the
python script directly succeeds. But for consistency, and for working in
cases when the python script can't be executed as such, make the
Python3_EXECUTABLE variable available as intended.

This PR contains initial changes for building and testing libomp on AIX.
More changes will follow.
- `KMP_OS_AIX` is defined for the AIX platform
- `KMP_ARCH_PPC` is defined for 32-bit PPC
- `KMP_ARCH_PPC_XCOFF` and `KMP_ARCH_PPC64_XCOFF` are for 32- and 64-bit
XCOFF object formats respectively
- Assembly file `z_AIX_asm.S` is used for AIX specific assembly code and
will be added in a separate PR
- The target library is disabled because AIX does not have the device
support
- OMPT is temporarily disabled

D150532 [OpenMP] Compile assembly files as ASM, not C
Since CMake 3.20, CMake explicitly passes "-x c" (or equivalent)
when compiling a file which has been set as having the language
C. This behaviour change only takes place if "cmake_minimum_required"
is set to 3.20 or newer, or if the policy CMP0119 is set to new.
Attempting to compile assembly files with "-x c" fails, however
this is workarounded in many cases, as OpenMP overrides this with
"-x assembler-with-cpp", however this is only added for non-Windows
targets.
Thus, after increasing cmake_minimum_required to 3.20, this breaks
compiling the GNU assembly for Windows targets; the GNU assembly is
used for ARM and AArch64 Windows targets when building with Clang.
This patch unbreaks that.

Previously, we tried to check whether the -std=c++17 option was
supported and manually add the flag. That doesn't work for compilers
that do support C++17 but use a different option syntax, like
clang-cl.
OpenMP itself probably doesn't specifically require C++17, therefore
CXX_STANDARD_REQUIRED is left off, but in some cases, we may
have code that only works in C++17 mode.
In particular, 46262cab24312c71717ca70a9d0700481aa59152 made a
refactoring that works when built with Clang in C++17 mode, but not
in C++14 mode. MSVC accepts the construct in both language modes.
For libomptarget, we've had specific checks that require C++17
(or the -std=c++17 option) to be supported. It's doubtful that
libomptarget has got any code which more specifically requires C++17;
this seems to be a remnant from when libomptarget was added
originally in 2467df6e4f04e3d0e8e78d662473ba1b87c0a885 / D14031.
At that point, the rest of OpenMP didn't require C++11, while
libomptarget did require it. Now, it's unlikely that anyone attempts
building it with a toolchain that doesn't support C++11.
At this point, we could also probably just set CXX_STANDARD_REQUIRED
to true, requiring C++17 as baseline for all the OpenMP libraries.
This fixes building OpenMP with clang-cl after
46262cab24312c71717ca70a9d0700481aa59152.

I think it's reasonable to upgrade to Python 3 for LIT test requirement because `lit` itself (`llvm/utils/lit/lit.py`) already switched to Python 3. In addition, LLVM already requires Python 3.6 to be the minimum version (https://llvm.org/docs/GettingStarted.html#software).

If testing for a warning option like -Wno-<foo> with GCC, GCC won't
print any diagnostic at all, leading to the options being accepted
incorrectly. However later, if compiling a file that actually prints
another warning, GCC will also print warnings about these -Wno-<foo>
options being unrecognized.
This avoids warning spam like this, for every OpenMP source file that
produces build warnings with GCC:
cc1plus: warning: unrecognized command line option ‘-Wno-int-to-void-pointer-cast’
cc1plus: warning: unrecognized command line option ‘-Wno-return-type-c-linkage’
cc1plus: warning: unrecognized command line option ‘-Wno-covered-switch-default’
cc1plus: warning: unrecognized command line option ‘-Wno-enum-constexpr-conversion’
This matches how such warning options are detected and added in
llvm/cmake/modules/HandleLLVMOptions.cmake, e.g. like this:
check_cxx_compiler_flag("-Wclass-memaccess" CXX_SUPPORTS_CLASS_MEMACCESS_FLAG)
append_if(CXX_SUPPORTS_CLASS_MEMACCESS_FLAG "-Wno-class-memaccess" CMAKE_CXX_FLAGS)
This also matches how LLDB warning options were restructured for
GCC compatibility in e546bbfda0ab91cf78c096d8c035851cc7c3b9f3.

On ARM, a C fallback version of __kmp_invoke_microtask is used,
which only handles up to a fixed number of arguments - while
many-microtask-args.c tests that the function can handle an
arbitrarily large number of arguments (the testcase produces 17
arguments).
On the CMake level, we can't add ${LIBOMP_ARCH} directly to
OPENMP_TEST_COMPILER_FEATURES in OpenMPTesting.cmake, since
that file is parsed before LIBOMP_ARCH is set. Instead
convert the feature list into a proper CMake list, and append
${LIBOMP_ARCH} into it before serializing it to an Python array.
Reapply: Make sure OPENMP_TEST_COMPILER_FEATURES is defined
properly in all other test subdirectories other than
runtime/test too.

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.

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.
