The compiler does not yet support everything needed to integrate well
with the MSVC ABI, in particular for runtime library selection and debug
format selection. Document them in FIXME comments and leave this
support undocumented by CMake for now.

Update the Clang version checks added by
* commit eacacc70fc (Clang: use -std=c++23 for Clang 17.0+,
2023-05-08, v3.27.0-rc1~115^2)
* commit 0183956d30 (Clang: C++26 support,
2023-05-16, v3.27.0-rc1~85^2)
to account for Android NDK r26's distribution of a Clang based on a
development version of LLVM/Clang 17.0 that pre-dated addition of
these flags.
Follow the pattern from commit 12e6796b62 (Android: Do not pass
non-existent Clang -std flags, 2018-04-02, v3.12.0-rc1~284^2),
which fixed the same problem for `-std=c++17`.

IntelLLVM 2023.0.0 and above emit this remark if `-g` is used without
any `-O<level>` flag, which is our default behavior. Add another flag
to suppress the remark.

These standard flags will be the same for other C++-derived languages
supported by nvcc. Follow the pattern from commit 25439c7d62 (Clang:
Refactor CXX standard flags ..., 2020-03-16, v3.18.0-rc1~362^2~4) to
factor them into a single macro so we can easily reuse them.
Issue: #25143
According to ARMClang documentation 6.20, the patch version number
should not include the last two digits of `__ARMCOMPILER_VERSION`,
which are reserved for internal use by ARM.
FreeBSD installs both LLVM and gcc with tools named after the
major version, in the form "clang<major>", such as "clang16".
Detect compilers named this way, and find the related toolchain
tools.
Revert commit 6b58cdd4cf (Ninja: Exclude NVHPC -Werror flags during
Fortran preprocessing, 2023-04-04). Since commit 9d40f01442 (NVHPC: Use
-Werror for COMPILE_OPTIONS_WARNING_AS_ERROR, 2023-04-13), `nvfortran`
can handle the plain `-Werror` flag during preprocessing.
Issue: #24665
The IAR linker silencer flag was previously hardcoded in
`CMAKE_${lang}_LINKER_EXECUTABLE`. Move the flag to a place that is
under the end user's control. The default behavior (silenced linker) is
not changed.
Fixes: #24828
The previously-used `-Werror all-warnings` is not supported by
the NVHPC suite of compilers. This previously worked since `-Werror`
was being used and `all-warnings` was being excluded.
We thought this was the correct syntax due to incorrect documentation
about `-Werror`, which stated the argument should be space-separated,
while it should actually be separated with `=` or `,`.
Issue: #24665
The Ninja generator preprocesses Fortran separately in order to scan for
module dependencies. NVHPC's `nvfortran` does not support its `-Werror`
flag while preprocessing with `-E`, so filter it out.

The settings added by commit 3fe8e33f27 (Clang: Record Clang 16.0 flags
for our experimental C++ modules support, 2023-03-03, v3.26.0-rc6~6^2)
work only for the GNU-like `clang++` front-end, and not for the
MSVC-like `clang-cl` on Windows.
Also quote the path to `clang-scan-deps` to support spaces in its path.
