VS 2017 version 15.8 introduced support for unity builds implemented
in part by the `$(VCTargetsPath)/Microsoft.Cpp.Unity.targets` file.
Do not enable unity builds on VS 15 versions that do not have that file.

llvm-rc requires preprocessed rc files. The CMake command line tool
cmake_llvm_rc enables channing the preprocessor call and the resource
compiler and make this appear as single compilation step.
When llvm-rc is detected as resource compiler, the RC compilation step
is set to use this command.
Simply remove `-Werror` flags from `CMAKE_<LANG>_FLAGS` to avoid failing
ABI detection if there happen to be warnings in the test project. For
example, `-Wunused-command-line-argument` warnings are common since the
ABI detection project may not exercise all the flags passed by users.
Fixes: #20305
CMake properly detects the toolkit directories as implicit system
includes, but CUDA compilers don't add explicit `-isystem` markups to
these directories when compiling CUDA code. Due to this limitation,
allow users to explicitly specify these directories as SYSTEM dirs.

In commit 97bca2f9fa (Android: Use unified toolchain in NDK r19+,
2019-07-26, v3.16.0-rc1~342^2) we hard-coded use of the unified
toolchain for NDK r19+ and skipped most of the old detection logic.
However, in that fast path we left out setting `_CMAKE_TOOLCHAIN_PREFIX`
for `CMakeFindBinutils` to select the matching binutils. Add it.

This adds logic to properly handle Swift executables. Only executables
marked as exporting symbols will now generate module interfaces for the
executable.
The `Assembler` test runs the C compiler in a custom command to generate
a `.s` file for the platform. When using the GNU-like Clang variant on
Windows, ensure that the custom command includes the MSVC runtime
library selection flags for Clang. That way the resulting `.s` file,
when assembled into a `.obj`, will tell the linker what runtime library
it needs.
This allows building .s/.S assembly code, and makes sure that the
`-fPIC` option isn't passed to the compiler (as it errors out on
Clang and causes a loud warning on GCC).
If no tests were found, the default behavior of CTest is to always log an
error message but to return an error code in script mode only. This option
unifies the behavior of CTest by either returning an error code if no tests
were found or by ignoring it.
