[modules] Simplify -cc1 interface for enabling implicit module maps.
...
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.

[modules] For an inheriting constructor, the inherited constructor is stored in

a map keyed off the canonical declaration. Don't try to set it if we're loading
some non-canonical merged declaration.

merging of namespace aliases across modules and improves source fidelity.

[modules] Fix deserialization cycle when loading a tag declaration with a typedef name for linkage purposes. When loading the type, delay loading its typedef until we've finished loading and merging the type. In its place, save out the name of the typedef, which we need for merging purposes.

[modules] When we merge redecl chains or mark a decl used with an update

record, mark all subsequent decls as 'used' too, to maintain the AST invariant
that getPreviousDecl()->Used implies this->Used.
