Erik Eckstein 23b4c6fc34 embedded: fix specialization of associated conformance entries in witness tables ...

When creating a specialized witness table, we need to get the right specialized conformance.
In IRGen don't emit associated conformance witness table entries if the protocol is not a class protocol.
In this case the associated type can never be used to create an existential. Therefore such a witness table entry is never used at runtime in embedded swift.

Fixes a compiler crash
