Revise the logic from commit v3.7.0-rc1~173^2~2 (GNU: Do not use
-fvisibility on AIX or HP-UX, 2016-09-03) to add a version check.
The GCC 7 release notes [1] state that visibility support has been
added for AIX 7.1 and above.

Shared libraries linked with CUDA now properly setup booth the correct
install_name but also specify headerpad_max_install_names so that the names
can be changed post build.
When using a real MSVC compiler for `C` or `CXX`, use the version of
that compiler for `MSVC_VERSION`. This is preferred over the MSVC
version that a non-MSVC compiler "simulates".
Fixes: #17468
Since commit v2.8.10~148^2~2 (Modernize MSVC compiler information files,
2012-08-23), the Windows-NMcl platform has been broken.
It's most likely not needed anymore.
Revert commit v3.7.0-rc1~25^2 (VS: Recognize VS/LLVM toolset names as
Clang, 2016-09-28). Since at least LLVM 5.0 the VS integration of the
LLVM toolchain now mimics cl and accepts MSVC-style command-line
arguments (unlike Microsoft Clang/C2).
Fixes: #17193, #17235
Since NDK commit 90ec78ffd96b87cd75d82575587ead14d6494df1 (Remove Clang
toolchain path from setup.mk, 2017-05-31) the `setup.mk` files for Clang
no longer hold the path to the `toolchains/llvm` directory. It has been
the same since NDK r11, so use that as the default.
Fixes: #17253
The VS environment script we load changes the working directory to
`%USERPROFILE%/source` if it exists. Set `VSCMD_START_DIR` to tell
the script to retain the current working directory.
The `crlf` attribute is deprecated in Git. This also changes the given
files to be in the index using LF newlines, but they will be checked
out with CRLF newlines due to the attribute.
If `CMAKE_SYSROOT` is set by the user (e.g. via the toolchain file) then
we do not set `CMAKE_SYSROOT_COMPILE` to our default. Fix our
references to the sysroot's `/usr/include` directory to use
`CMAKE_SYSROOT_COMPILE` only if it is set and else `CMAKE_SYSROOT`.
Fixes: #17096
The logic added in commit v3.6.0-rc1~30^2 (Add a variable to specify
language-wide system include directories, 2016-05-24) to use
`CMAKE_<LANG>_STANDARD_INCLUDE_DIRECTORIES` incorrectly filters them by
`CMAKE_<LANG>_IMPLICIT_INCLUDE_DIRECTORIES`. Rather than recognizing
this, commit v3.8.0-rc1~60^2 (Android: Pass sysroot include directory
explicitly, 2017-01-20) worked around the problem by incorrectly
removing `/usr/include` from `CMAKE_<LANG>_IMPLICIT_INCLUDE_DIRECTORIES`
so it worked in `CMAKE_<LANG>_STANDARD_INCLUDE_DIRECTORIES`.
By not filtering out `/usr/include` from user-specified include
directories, we allow the code
include_directories(${CMAKE_SYSROOT}/usr/include)
to place the include directory too early on the command line.
Fix support for standard include directories to not be filtered by
implicit include directories, and do not remove `/usr/include` from the
list of implicit include directories for Android builds. Add a test
case to verify that an explicit `/usr/include` is ignored in favor
of the standard directory at the end.
Fixes: #17059
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.

Fixes: #16584
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 `--out-fmt-ihx` option added by commit v2.6.0~1253 (...use
--out-fmt-ihx to enforce .ihx files, 2007-08-15) may interfere with
options requested by the user. Also, when no linker output is
specified, SDCC outputs Intel Hex by default anyway.
Use `cmake_host_system_information` to query the VS Installer tool for
the locations of VS versions since VS 2017 does not provide registry
entries anymore. Add a loop to simplify addition of future versions.
