modules to preprocessing of nested .pcm files.
Making those module files available results in loading more .pcm files than
necessary, and potentially in misbehavior if a module makes itself visible
during its own compilation (as parts of that module that have not yet been
processed would then become visible).

and it has an include guard, produce callbacks for a module import, not for a
skipped non-modular header.
Fixes -E output when preprocessing a module to list these cases as a module
import, rather than suppressing the #include and losing the import side effect.

These pragmas are intended to simulate the effect of entering or leaving a file
with an associated module. This is not completely implemented yet: declarations
between the pragmas will not be attributed to the correct module, but macro
visibility is already functional.
Modules named by #pragma clang module begin must already be known to clang (in
some module map that's either loaded or on the search path).

object. In such a case, use the TU's DC for merging global decls rather than
giving up when we find there is no TU scope.
Ultimately, we should probably avoid all loading of decls when preprocessing,
but there are other reasonable use cases for loading an AST file with no Sema
object for which this is the right thing.
