23b4c6fc - embedded: fix specialization of associated conformance entries in witness tables

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 rdar://146448091
