Pass the value to the Swift compiler driver via `-sdk`. We already do
this for C/C++ via `-isysroot`.
This fixes command-line builds on macOS 10.15 with Xcode 11 Swift tools.
Fixes: #19880
`-num-threads` is for the threading, not the job control. Use `-j` to
launch the parallel jobs. This enables parallel builds for Swift again
after driver updates preventing the parallelization through
`-num-threads`.
Some unset calls were added by commit 079b8e2916 (Clang: prefer lld-link
over link.exe, 2019-07-11, v3.16.0-rc1~161^2~2) but they are unnecessary
since commit 3a82ef78eb (CMakeFindBinUtils: Rename and unset variables
for additional names, 2019-07-23, v3.16.0-rc1~332^2~2).

The HIP clang makes 2 passes when compiling HIP programs: the DEVICE
pass and the HOST pass. For openmp, the `-fopenmp` option is only
passed to the HOST compilation pass. Therefore, the small test that
CMake uses for OpenMP detection fails to compile, and CMake reports
failure to detect OpenMP support in the compiler. The suggested
solution is to add check for `__HIP_DEVICE_COMPILE__` macro defined by
HIP clang for the DEVICE pass to the OpenMP detection test.
Macports installs into `include/postgresql${suffix}`. Add this to the
list of supported suffixes. Also copy the non-server
`postgresql/${suffix}` path.
For the Intel Compiler for Windows we have some subtle preprocessor
checks in compiler feature detection to detect C++11 and C++14 modes.
Use these when detecting the default C++ dialect too.
The same is done for the C and CXX language. This initializes
compiler flags like the sysroot path or deployment target.
Closes: #19794

When using `-T v142,version=14.22` the `.props` file location is
different starting with version `14.20` than it was in `14.16` and
below. Adapt the path based on the version.

Merge-request: !3811
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.
