c++: Handle error header names in modules [PR107594]
When there are no include paths while preprocessing a header-name token,
an empty STRING_CST is returned. This patch ensures this is handled when
attempting to create a module for this name.
PR c++/107594
gcc/cp/ChangeLog:
* module.cc (get_module): Bail on empty name.
