to the original module map.
Also use the path and name of the original module map when emitting that
information into the .pcm file. The upshot of this is that the produced .pcm
file will track information for headers in their original locations (where the
module was preprocessed), not relative to whatever directory the preprocessed
module map was in when it was built.

and it has an include guard, produce callbacks for a module import, not for a
skipped non-modular header.
Fixes -E output when preprocessing a module to list these cases as a module
import, rather than suppressing the #include and losing the import side effect.
