If a protocol witness table requires instantiation, the runtime needs to call the witness table accessor when looking up the conformance in swift_conformsToProtocol(). We had a bit of code for this already, but it wasn't fully hooked up. Change IRGen to emit a reference to the witness table accessor rather than the witness table itself if the witness table needs instantiation, and add support to the runtime for calling the accessor.
