[PATCH] D37299: [Modules] Add ability to specify module name to module file mapping in a file

rsmith added a comment.

I'm still unconvinced that this mechanism is worth supporting.

The use case of putting this information into .d files doesn't make sense to me. .d files are generally outputs of prior compilations, whereas this information is a compilation input, needed in every compilation (including the first), and must be eagerly updated if a change to the source code adds a new dependency.
