When going to dictionary formats derived from the function instantiations, I had broken out noder.Assignop() to deal specially with shape types, but didn't quite get the tricky case right. We still need to allow conversion between shape types, but if the destination is an interface, we need to use CONVIFACE rather than CONVNOP. Fixes #48453.
