Everywhere there's a `SWIFT_MODULE_DEPENDS_LINUX Glibc`, there should be
a corresponding `SWIFT_MODULE_DEPENDS_LINUX_STATIC Musl`.
This usually won't bite us, depending on build order and parallelism, but
I hit one of these yesterday so went looking to see if there were any
others.

This patch goes through and adds zippering and the swift module
dependencies to a bunch of pieces of the swift runtimes. Here's to
hoping I hit everything that needed to be hit. :D
With this patch, I'm seeing the appropriate modules under
lib/swift/maccatalyst, so things seem to be working right.
* Implement String.WordView
* Add isWordAligned bit
* Hide WordView for now (also separate Index type)
add bidirectional conformance
Fix tests
* Address comments from Karoy and Michael
* Remove word view, use index methods
* Address Karoy's comments

This replaces swiftMSVCRT with swiftCRT. The big difference here is
that the `visualc` module is no longer imported nor exported. The
`visualc` module remains in use for a singular test wrt availability,
but this should effectively remove the need for the `visualc` module.
The difference between the MSVCRT and ucrt module was not well
understood by most. MSVCRT provided ucrt AND visualc, combining pieces
of the old MSVCRT and the newer ucrt. The ucrt module is what you
really wanted most of the time, however, would need to use MSVCRT for
the convenience aliases for type-generic math and the deprecated math
constants.
Unfortunately, we cannot shadow the `ucrt` module and create a Swift SDK
overlay for ucrt as that seems to result in circular dependencies when
processing the `_Concurrency` module.
Although this makes using the C library easier for most people, it has a
more important subtle change: it cleaves the dependency on visualc.
This means that this enables use of Swift without Visual Studio for the
singular purpose of providing 3 header files. Additionally, it removes
the need for the installation of 2 of the 4 support files. This greatly
simplifies the deployment process on Windows.
Commit for CMake and build scripts to recognize OpenBSD. To keep this
commit relatively short, this just deals with the rather simple and
uncontroversial changes to the build system.
Note that OpenBSD calls "x86_64" as "amd64", Since the Swift stdlib will
be put in a subdirectory named after ARCH, to ensure the standard
library is properly found later, we use the native architecture name for
OpenBSD in the build system rather than trying to deal with the
difference the other way around.
There are situations where you want to build against a libc that is out
of tree or that is not the system libc (Or for cross build scenarios).
This is a change for passing the -sdk and include paths for things like
this.
The pthread dependency has been lifted through the Windows port
generalising the SwiftThreadExtras. Enable building these unit test
binaries which are needed for the validation test suite.
The key thing here is that all of the underlying code is exactly the same. I
purposely did not debride anything. This is to ensure that I am not touching too
much and increasing the probability of weird errors from occurring. Thus the
exact same code should be executed... just the routing changed.
76ef276 made the compiler autolink libraries more eagerly than before.
This normally wouldn't affect the products we build with CMake, but
when an overlay is autolinked the compiler also puts in a dummy symbol
to make sure it gets linked. So now we have to link to the overlay
directly.
From the Swift documentation:
"If you define an optional variable without providing a default value,
the variable is automatically set to nil for you."
