Add support for calls to dependent names within templates, e.g.,
template<typename T> void f(T x) {
g(x); // g is a dependent name, so don't even bother to look it up
g(); // error: g is not a dependent name
}
Note that when we see "g(", we build a CXXDependentNameExpr. However,
if none of the call arguments are type-dependent, we will force the
resolution of the name "g" and replace the CXXDependentNameExpr with
its result.
GCC actually produces a nice error message when you make this
mistake, and even offers to compile your code with -fpermissive. I'll
do the former next, but I don't plan to do the latter.
