Subject: [PATCH 1/2] [Clang][Darwin] Introduce `SubFrameworks` as a SDK
default location
* Have clang always append & pass `System/Library/SubFrameworks` when
determining default sdk search paths.
* Teach `clang-installapi` to traverse there for framework input.
* Teach `llvm-readtapi` that the library files (TBD or binary) in there should be considered
private.
