Make named repeated parameters discoverable during PatMat.
They used to be discoverable using repeatedType, but ElimRepeated eliminates it.
Instead I'm using internal synthetic Typed nodes name, similar to how it's done for non-star Wildcards.
This makes handling Wildcards and Wildacard_Star more symmetric in patmat.
