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 adds -nostdsysteminc to the %clang_cc1 expansion, which should
make it harder to accidentally write tests that depend on headers in
/usr/include. It also updates a few tests that use -isysroot <x> and a
darwin triple to omit the triple and use -isystem <x>/usr/include
instead, making them a little bit more general.
Incidentally, this fixes a test failure I'm seeing on darwin in
Modules/stddef.c, that happens because my system finds a stddef.h in
/usr/include.

When enabled, always validate the system headers when loading a module.
The end result of this is that when these headers change, we will notice
and rebuild the module.
