c++: Fix comparison of fn() and ns::fn() [PR90711]
The resolution of CWG issue 1321 clarified that when deciding whether two
expressions involving template parameters are equivalent, two dependent
function calls where the function is named with an unqualified-id are
considered to be equivalent if the name is the same, even if unqualified
lookup finds different sets of functions. We were wrongly treating
qualified-ids the same way, so that EXISTS and test::EXISTS were considered
to be equivalent even though they are looking up the name in different
scopes. This also causes a mangling bug, but I don't think it's safe to
fix
that for GCC 10; this patch just fixes the comparison.
