Since commit v3.9.0-rc1~55^2 (Improve Doxygen support, 2017-04-10) we
accidentally leave a non-prefixed internal `result` variable set.
This may interfere with project code. Add a prefix to avoid this.
In commit v3.9.0-rc3~3^2 (Android: Add support for unified headers,
2017-06-12) we accidentally constructed the unified header include
directories from the linking sysroot. Construct them from the
compiling sysroot instead.
Fixes: #16584
We only define `INTERPROCEDURAL_OPTIMIZATION` behavior for C, CXX, and
Fortran languages. Do not try to enable support for other languages.
Furthermore, each language builds with a different compiler, so check
for support by CMake and the compiler for each language independently.
Fixes: #16944
The CUDA compiler automatic deprecation warnings are pure noise when
doing device linking, and should be suppressed to reduce the amount of
confusion from users.
The unified headers are preferred as of NDK r15, so use them by default
if available and provide an option to use the deprecated headers.

The change in commit v3.8.0-rc1~60^2 (Android: Pass sysroot include
directory explicitly, 2017-01-20) does not make sense when compiling
with a standalone toolchain which is tied to a single API version.
Drop the explicit include directory so that the compiler uses its
default system include order.
Fixes: #16954
The imported targets added by commit v3.9.0-rc1~55^2 (Improve Doxygen
support, 2017-04-10) need to be guarded against duplicate creation on
multiple inclusion.

This modification is necessary if the GSL libraries are installed
in an installation layout without Release and Debug subdirectories,
for example when installed by vcpkg .
There are no specific options for MSVC to set language standards, but
set them as empty strings anyways so the feature test infrastructure
can at least check to see if they are defined.
Add default implementations for the cmake_record_lang_compile_features
macros. All implementations of this are the same so it can be safely
factored out to a common implementation.

In the bootstrap script, we want to be able to extract language standard
flags using sed. Make sure the content of the flag varianbles can be
passed unmodified to the compiler.
