c++: using in diagnostics [PR102987]
The expression pretty-printing code crashed on a location wrapper with no
type, and didn't know what to do with a USING_DECL.
PR c++/102987
gcc/cp/ChangeLog:
* error.cc (dump_expr): Handle USING_DECL.
[VIEW_CONVERT_EXPR]: Just look through location wrapper.
gcc/testsuite/ChangeLog:
* g++.dg/diagnostic/using1.C: New test.
