c++: Export usings referring to global module fragment [PR109679]
This patch stops 'add_binding_entity' from ignoring all names in the
global module fragment, since they should still be exported if named
in an exported using-declaration.
PR c++/109679
gcc/cp/ChangeLog:
* module.cc (depset::hash::add_binding_entity): Don't skip names
in the GMF if they've been exported with a using declaration.
gcc/testsuite/ChangeLog:
* g++.dg/modules/using-11.h: New test.
* g++.dg/modules/using-11_a.C: New test.
* g++.dg/modules/using-11_b.C: New test.
