We used to have a flag to enable module maps, and two more flags to enable
implicit module maps. This is all redundant; we don't need any flag for
enabling module maps in the abstract, and we don't usually have -fno- flags for
-cc1. We now have just a single flag, -fimplicit-module-maps, that enables
implicitly searching the file system for module map files and loading them.
The driver interface is unchanged for now. We should probably rename
-fmodule-maps to -fimplicit-module-maps at some point.

This just tweaks the fix from r224892 (which handled PCHs) to work with
modules, where we will serialize each method individually and hence the
hasMoreThanOneDecl bit needs to be updated as we add the methods.
