[Patch] Disable -Wtaulological-compare for substituted template types

[David Blaikie]

Looks pretty reasonable - but are these two separate code changes, or do
they interrelate in some way? If they're separate changes that can have
separate test cases, it'd be nice to commit them each in their on commit
just for clarity.

Have you considered/plan to look at non-type template parameters?

template<int Num>
bool greater(unsigned Val) {
  return Val >= Num;
}

... greater<0>(42); ...

I'm not sure if this tickles the same kind of problem or not - but might be
worth checking.
