swift-mirror/test/Casting/fast_class_casts.swift
Erik Eckstein 2527d3765e IRGen: fix how metadata is loaded for fast class casting 
Pass the correct type to `emitHeapMetadataRefForHeapObject()`.
Fixes a runtime crash in case a class protocol is cast to a final swift class, where the actual object is an ObjectiveC class instance.
