Fold congruent type barriers
The testcase in bug 1111000 uses a lot of variables in an outer scope, so we have GETALIASEDVAR ops with type barriers. We're able to fold the loads but not the type barriers, so we end up with many barriers testing the same types and this also inhibits other GVN optimizations. This patch allows us to fold them and is at least a 10% win on that testcase.
