[dev.typeparams] Fix the types of the OFUNCINST nodes in noder2

types2 doesn't actually give us the type of an instantiated
function/method after the type args have been applied. So, do a
substitution at the point that we create the OFUNCINST nodes.

We also needed to add in translation of the typeparams of a function
signature in the type substituter. If the type params of the function
become all concrete after the substitution, then we just drop them,
since the whole signature must now be concrete.
