When cross-compiling with Xcode our compiler id test binary may be
compiled with multiple architectures. The INFO strings should be
identical and therefore de-duplicated. However, this can be broken by
stray text that happens to sit immediately before or after an INFO
string. Filter out such text so we can match clean INFO strings.

This change was originally made by commit 74b1c9fc8e (Explicitly specify
language flag when source LANGUAGE property is set, 2020-06-01,
v3.19.0-rc1~722^2), but it was reverted by commit 30aa715fac (Revert
"specify language flag when source LANGUAGE property is set",
2020-11-19) to restore compatibility with pre-3.19 behavior.
Implement the change again, but add policy CMP0119 to make this change
while preserving compatibility with existing projects.
Note that the `Compiler/{Clang,Intel,MSVC}-CXX` modules do not need to
specify `-TP` for their MSVC-like variants because we already use the
flag in `CMAKE_CXX_COMPILE_OBJECT`. Similarly for `Compiler/XL-CXX`
and `Platform/Windows-Embarcadero`.
Note also that this does not seem possible to implement for XL C.
Even with `-qsourcetype=c`, `xlc` complains about an unknown suffix:
`1501-218 (W) file /.../AltExtC.zzz contains an incorrect file suffix`.
It returns non-zero even with `-qsuppress=1501-218`.

When preprocessing the rc file using the clang gnu front end we need to
force the source file type to a c file for the preprocessing to take
place.

Customer reported problems detecting the Cray compiler on their Apollo80
system. We were checking for the __CRAYXC and __CRAYXE predefined
macros. These macros reflect the platform that the compiler is running
on, i.e. Cray XC and Cray XE machines. Naturally, this didn't work on
Apollo80.
This commit uses the official Cray compiler identification macros which
are defined on every platform:
CCE Version C Macro C++ Macro Fortran Macro
============ ======== ========= =============
version < 9 _CRAYC _CRAYC _CRAYFTN
version >= 9 __cray__ __cray__ _CRAYFTN

NVCC's default architecture may be newer than the one supported by the
machine's GPU.
In such cases it's useful to have an environment variable for initializing
CMAKE_CUDA_ARCHITECTURES to avoid specifying it for every invocation.
Each source compilation generates a dependencies file. These dependencies
files are consolidated in one file per target. This consolidation is done
as part of command 'cmake -E cmake_depends` launched before evaluation of
makefile dependency graph.
The consolidation uses the same approach as `CMake` dependencies management.
Fixes: #21321
These changes are in preparation of compiler generated dependencies support
for Makefiles generators
* compiler output and dependency target can be different for Makefiles generators
* resolve inconsistency naming for dependency file place-holder
Rename the `CheckPIESupported` helper functions so that they
don't clobber other internal functions. Also rename them to
document they can't be unified with `CheckCompilerFlag`.
Fixes: #21497
