In commit 8218aed118 (IntelLLVM: support marking include paths as SYSTEM
directories, 2023-08-15, v3.29.0-rc1~81^2) this flag was added for the C
and C++ compilers, but was accidentally added for Fortran too. Remove
it for the latter, as it is unsupported.
Issue: #25807
Apply the fix from commit 1ec6485c6a (Support duplicate object names in
large archives, 2014-04-16, v3.1.0-rc1~629^2) to the IPO-specific
archiving rules. Use "quick append" instead of "replace".
Fixes: #25675
Issue: #14874
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.
Don't initialize the other CMAKE_<LANG>_COMPILER_PREDEFINES_COMMAND
variables.
The only language variant that is used is
CMAKE_CXX_COMPILER_PREDEFINES_COMMAND, and the other language variants
contained invalid, namely C++-specific commands.
Fixes: #23968
Update the compiler options table added by commit 76a08cd253
(COMPILE_WARNING_AS_ERROR: Add options to treat warnings as errors,
2022-04-21, v3.24.0-rc1~173^2) to use the Intel Fortran compilers'
dedicated `-warn*` flags.
Replicate and adapt Linux IPO options for Intel for IntelLLVM compilers
on Linux and Windows.

Add `COMPILE_WARNING_AS_ERROR` target property and supporting
`CMAKE_COMPILE_WARNING_AS_ERROR` variable.
`COMPILE_WARNING_AS_ERROR` is initialized by
`CMAKE_COMPILE_WARNING_AS_ERROR`. It is a boolean variable. If it is
true, it expands to a different flag depending on the compiler such that
any warnings at compile will be treated as errors.
Supports compiler ids that I could find a relevant flag for.
`clang-cl` supports the `-imsvc` flag to tell the compiler an include
directory is intended for system paths. `icx` does not accept this
flag, even on MSVC platforms, so do not tell CMake that it exists.

Using a single ID 'IntelLLVM' for the suite of Intel compilers based on
the LLVM backend. The 'IntelLLVM' ID are used for C, C++, and Fortran.
Data Parallel C++ will be handled in a separate commit.
The C and C++ definitions are based on the Clang definitions. The Intel
LLVM-based C and C++ compilers are based on the Clang front end, so
existing Clang options are more likely to be a good match than options
for the older Intel compilers.
Fortran is based on the older Fortran front end with the LLVM backend.
It has a similar interface to the older versions, though many options
are shared with the C and C++ compilers.
