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.

The attempt in r212980 was broken because we might not fail if
LLVM_ON_UNIX is enabled for cross compiling to Windows, and it didn't
consider mingw either.

Just because we can open a directory named "COcoa.framework" doesn't
mean we should provide a "COcoa" module on a case-insensitive filesystem.
