Richard Smith 4df6093ca3 [modules] Make sure macros get made visible in the top-level file if we've got
local submodule visibility enabled; that top-level file might not actually be
the module includes buffer if use of prebuilt modules is disabled.

Richard Smith 47972afd10 [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.

Richard Smith a0aafa3853 [modules] If we see a #include that maps to a module, but use of precompiled modules is disabled, track submodule visibility anyway if -fmodules-local-submodule-visibility is enabled. This, in effect, gives modules semantics but without precompilation.

Richard Smith 4241314164 [modules] Add local submodule visibility support for declarations.
With this change, enabling -fmodules-local-submodule-visibility results in name
visibility rules being applied to submodules of the current module in addition
to imported modules (that is, names no longer "leak" between submodules of the
same top-level module). This also makes it much safer to textually include a
non-modular library into a module: each submodule that textually includes that
library will get its own "copy" of that library, and so the library becomes
visible no matter which including submodule you import.
