Hmm, maybe it can't (the "aliases" map to the same symbol). But at least
if I produce another decl with say, attribute(regparm), and that gets
picked even though I didn't call it then it would be wrong-code
(of course that decl is technically invalid as the symbol it refers to
has different calling conventions).
