When we reach the end of a #include of a header of a local submodule that we

textually included, create an ImportDecl just as we would if we reached a
#include of any other modular header. This is necessary in order to correctly
determine the set of variables to initialize for an imported module.

This should hopefully make the modules selfhost buildbot green again.
