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.

encountered any definition for the class; this happens when the definition is
added by an update record that is not yet loaded. In such a case, eagerly pick
the original parent of the member as the canonical definition of the class
rather than muddling through with the canonical declaration (the latter can
lead to us failing to merge properly later if the canonical definition turns
out to be some other declaration).
