c++: visibility of local extern [PR103291]
When setting up the hidden namespace-scope decl for a local extern, we also
need to set its visibility.
PR c++/103291
gcc/cp/ChangeLog:
* name-lookup.cc (push_local_extern_decl_alias): Call
determine_visibility.
gcc/testsuite/ChangeLog:
* g++.dg/ext/visibility/visibility-local-extern1.C: New test.
