In commit 1293ed8507 (ParseImplicitIncludeInfo: keep implicit incl.
consistent when rerunning cmake, 2019-01-30, v3.14.0-rc1~26^2) we did
not account for `CMAKE_<LANG>_STANDARD_INCLUDE_DIRECTORIES`. This
variable lets platform modules or toolchain files specify directories
that are to be explicitly passed as standard include directories. These
include directories are used by the test project from which we extract
implicit include directories so they appear in the parsed results
whether or not the compiler really considers them implicit. Exclude
these entries from the computed implicit include directories since they
are not actually implied by the compiler when we invoke it with
"standard" include directories passed explicitly.
Instead teach the build system generators to treat the "standard"
directories as implicit for purposes of excluding them from appearing
earlier in the compiler command line due to `include_directories` and
`target_include_directories` calls.
Issue: #18936, #18944
`CMAKE_<LANG>_STANDARD_INCLUDE_DIRECTORIES` is meant to unconditionally
add explicitly specified include directories to compile lines. In
commit 5f34bdc7f9 (cmLocalGenerator: Refactor
`GetIncludeDirectoriesImplicit` method, 2019-01-25, v3.14.0-rc1~65^2~1)
a condition was accidentally added to exclude implicit include
directories. Drop that condition.
Fixes: #18936
Since commit 7cd65c97fa (Add CMAKE_SYSROOT variable to set --sysroot
when cross compiling., 2013-04-13, v3.0.0-rc1~342^2) we have prefixed
the value of `CMAKE_SYSROOT` to implicit include directories. This was
done because we hard-coded `/usr/include` as an implicit include
directory without accounting for the sysroot. Instead we should prefix
the hard-coded paths when they are constructed. Update the
`Platform/UnixPaths` module to do this as `Platform/Darwin` already
does.
Since commit 5990ecb741 (Compute implicit include directories from
compiler output, 2018-12-07, v3.14.0-rc1~108^2) the values of the
`CMAKE_<LANG>_IMPLICIT_INCLUDE_DIRECTORIES` variables are computed from
a real compiler invocation so they already account for the sysroot
prefix. In commit 6fc3382944 (Update logic for sysroot in detected
implicit include directories, 2019-02-13, v3.14.0-rc2~6^2) we attempted
to apply the prefix conditionally, but that is incorrect because the
compiler's real implicit include directories are not all under the
sysroot. Instead assume that all implicit include directories in
`CMAKE_<LANG>_IMPLICIT_INCLUDE_DIRECTORIES` already have the sysroot
prefix if needed. Code that constructs the value must be responsible
for that because it is the only place that knows.
When building a swift object, we emit a partial swiftmodule and swiftdoc
that must be merged at the end. However, in order to do that, we need
to enumerate the swiftmodules and swiftdocs. As a result, the path must
be known to CMake. Rather than hardcoding the rules into CMake, create
a source property that we can query. This will allow us to create a
final placeholder to emit the merge rule.

They are unused, but if someone used them they would lead to
problems since they would copy the internal raw pointers
and the destructor would cause double delete
The quoting added by commit 8c5221fb1f (try_compile: Preserve special
characters in COMPILE_DEFINITIONS, 2019-01-21, v3.14.0-rc1~108^2~3)
broke the case that the `COMPILE_DEFINITIONS` value contains a `;`.
Without the quoting the `;` would be generated literally in an unquoted
argument in the test `CMakeLists.txt` file and would then be expanded.
With quoting the `;` is preserved, which is not the old behavior.
Fix this by expanding the `;`-list ahead of time. Add test cases for
behavior with both `#` and `;`.
This was noticed with the PGI compiler where we set
`CMAKE_CXX*_STANDARD_COMPILE_OPTION` to values like `--c++17;-A`. The
symptom had also been observed while preparing commit ef8f237686
(ParseImplicitIncludeInfo: add SunPro Fortran and PGI compiler, Cray
fix, 2019-01-29, v3.14.0-rc1~26^2~2) but was not recognized at the time
as a regression. Revert the workaround added by that commit.

The naming convention for submodule files varies across compilers. Add
a table to the compiler information modules and thread the information
through to the Fortran module dependency parser. Fill out the table for
compiler ids known to support Fortran submodules.

The check added by commit 0a29a31161 (VS2017: Verify Windows 8.1 SDK

`windows.h` within the SDK, leading to it never being detected.

This allows us to set the proper link name for the Swift library
(soname). Because this needs to be passed to the object being compiled,
we need to create a new placeholder so that it can be sent along to the
frontend. Default to the target name unless it is explicitly provided.
The `cmsys/Enconding.h` include had a typo in its surrounding ifdef,
possibly causing a missing function declaration (`cmsysEncoding_DupToWide`).
As this is C code, this resulted in the code compiling, but with a truncated
return value, possibly causing crashes.
Since commit 5990ecb741 (Compute implicit include directories from
compiler output, 2018-12-07, v3.14.0-rc1~108^2) the values of the
`CMAKE_<LANG>_IMPLICIT_INCLUDE_DIRECTORIES` variables are computed from
a real compiler invocation. In this case the paths under the sysroot
should already have the sysroot prefix so we should no longer have to
add the sysroot prefix. However, it is also possible for project code
to add its own paths to `CMAKE_<LANG>_IMPLICIT_INCLUDE_DIRECTORIES`
without the sysroot prefix and expect the historical addition of the
sysroot prefix to be preserved.
Try to account for both cases by conditionally adding the sysroot prefix
on implicit include directories that do not already have it.
