Ensure that we link `swift_CompilerPluginSupport` into the compiler and
SourceKit, and set the rpath appropriately to find the library in its
installed location.
A number of driver tests copy the driver executable into a temporary
directory to isolate it from the build tree. Also copy the plugin
support library into its appropriate place near the driver executable
to ensure these tests keep working. To help with this, add a
`swift_swift_parser` lit feature, which we can use in tests that
involve the new parser's capabilities.
Clang enforces a minimum 13.1 deployment target. The driver, API
checker, and various tests assume 13.0 is a valid minimum. Update these
to reflect the actual 13.1 minimum.

Adding build modes for libswift: off, hosttools, bootstrapping, bootstrapping-with-hostlibs
The two bootstrapping modes are new. For details see libswift/README.md
The compiler_rt static library for iOS simulator is now packaged in a separate static archive from the one for iOS devices. Adjust linker invocation to match.
Fixes rdar://66192830 / rdar://66060312.
Hardlinking to a symlink is not permitted, so use "swift-frontend"
instead of "swift" as the hard-link target.
Also, update one Linux-specific test to check for swift-frontend.
Add support in the driver and frontend for macCatalyst target
targets and library search paths.
The compiler now adds two library search paths for overlays when compiling
for macCatalyst: one for macCatalyst libraries and one for zippered macOS
libraries. The macCatalyst path must take priority over the normal macOS path
so that in the case of 'unzippered twins' the macCatalyst library is
found instead of the macOS library.
To support 'zippered' builds, also add support for a new -target-variant
flag. For zippered libraries, the driver invocation takes both a -target and a
-target-variant flag passes them along to the frontend. We support builds both
when the target is a macOS triple and the target variant is macCatalyst and
also the 'reverse zippered' configuration where the target is macCatalyst and the
target-variant is macOS.
The Driver/linker-clang_rt test had some of its run lines with incorrect prefixes.
(For example, the prefix for the iOS tests was 'IOS' rather than 'CHECK-IOS'). The
effect is that the CHECK lines in the test weren't actually used and so little was
being tested.
The commits updates the --prefix arguments so that the CHECK lines are active.
This also updates the test to specify the current behavior: namely that the
compiler-rt path is in "/lib/swift/clang/lib/darwin/" rather than "/lib/clang/darwin/".
I've also updated one of the tvOS lines to use the "tvos" in the target rather than
"ios". I suspect that was typo that wasn't caught the test wasn't running.
