Duncan P. N. Exon Smith 70d759b4eb Modules: Add LangOptions::CacheGeneratedPCH ...

Add an option to cache the generated PCH in the ModuleCache when
emitting it.  This protects clients that build PCHs and read them in the
same process, allowing them to avoid race conditions between parallel
jobs the same way that Clang's implicit module build system does.
