ccc: Implement support clang PTH using gcc PCH style interface.
This requires some hackery, as gcc's PCH mechanism changes behavior,
whereas while PTH is simply a cache. Notably:
- Automatically cause clang to load a .pth file if we find one that
matches a command line -include argument (similar to how gcc
looks for .gch files).
- When generating precompiled headers, translate the suffix from .gch
to .pth (so we do not conflict with actual gcc PCH files).
- When generating precompiled headers, copy the input header to the
same location as the output PTH file. This is necessary because gcc
supports -include xxx.h even if xxx.h doesn't exist, but for clang
we need to actually have the contents of this file available.
