5341f5e4a1 CUDA: get header deps from compiler invocation when possible
7f15c99851 CUDA: forward unknown flags to host compiler when possible.
Acked-by: Kitware Robot <kwrobot@kitware.com>
Merge-request: !4099
Starting with CUDA 10.2 the nvcc compiler has gained support
to automatically forward unknown flags to the host compiler.
This behavior is highly desired as projcts that mix CUDA, C, C++
run into situation where flags such as `-pthread` which aren't
supported by nvcc, are being applied to all source files and
therefore break CUDA compilation.
The Ninja generator's support for Fortran requires that source files
be preprocessed explicitly first. However, the `xlf` compiler does
not have a simple `-E` option or equivalent to do preprocessing.
The only documented way to get preprocessed output is to use `-d`
to leave it behind, but only at an inflexible location.
Instead, create our own `cpp` wrapper script and substitute it for the
real preprocessor using `-tF -B ...`. Teach the wrapper to map the
`cpp` output to the location we need and then invoke the real `cpp`
underneath.

Revert commit b2fd479df5 (FindBinUtils: Use the compiler to get the path
to compiler tools, 2019-09-22, v3.16.0-rc1~51^2). The compiler's answer
may incorrectly come from the `PATH`. Another approach will be needed.

Add entries in Modules and Modules/Platform to support
Objective-C++ compiler determination and identification.
Add Modules to check Objective-C++ compiler flags, source
compilations, program checks, etc...
Use OBJCXX as the designator of the language, eg:
project(foo OBJCXX)
Add various tests for Objective-C++ language features. Add
tests to preserve C++ handling of .M and .mm files when
Objective-C++ is not a configured language.

The Intel Fortran compiler supports an extension that allows conditional
compilation based on preprocessor definitions specified on the command
line even when not preprocessing.
Fixes: #19664
Beginning with the 19.06 release of the Cray Programming Environment, the
default linking mode on XC Cray systems is dynamic instead of static.
This updates the CrayPrgEnv compiler wrappers to detect the PE version
being used and behave accordingly.
Since commit d44c0db0b2 (clang: setup correct configuration in gnu mode,
2019-02-20, v3.15.0-rc1~41^2~5) we support the GNU-like Clang that
targets the MSVC ABI. However, Clang cannot compile with the MSVC
standard library unless it runs in a mode aware of C++14 (since MSVC
itself does not even have a lower mode). When `CMAKE_CXX_STANDARD` is
set to 98 or 11, use C++14 anyway.
Since Clang's default mode is aware of C++14, another option is to not
add any flags for 98 or 11. However, if a future Clang version ever
defaults to a higher C++ standard, setting the standard to 98 or 11
should at least not use a mode higher than 14.
Also revert test updates from commit 4819ff9647 (Tests: fix failures
with gnu mode clang on windows, 2019-03-21, v3.15.0-rc1~41^2~3) that
were meant to work around the standard selection problem.

Use the infrastructure added by commit 646fb1a646 (CompileFeatures:
memoize C++ compilers with full language level support, 2019-03-27) to
avoid using a `try_compile` to check for C++14 feature support when the
running compiler is known to have all features.
