[fullcodegen] Add support for %_GetSuperConstructor.

Since the parser now desugars super constructor calls to simple
primitives, we can also easily optimize those in fullcodegen w/
just a few simple lines of native code per architecture.  This
code in particular should be fast, so it seems worth the code
in fullcodegen.
