Member predicate Method::hasQualifiedName
Holds if this method has name m and belongs to the method set of a type T or *T where
T is declared in package pkg and has name tp.
Note that meth.hasQualifiedName(pkg, tp, m) is almost, but not quite, equivalent to
exists(Type t | t.hasQualifiedName(pkg, tp) and meth = t.getMethod(m)): the latter
distinguishes between the method sets of T and *T, while the former does not.
