parameter types to be ill-formed. However, it relies on the completeness of method parameter types when producing metadata, e.g., for a protocol, leading IR generating to crash in such cases. Since there's no real way to tighten down the semantics of Objective-C here without breaking existing code, do something safe but lame: suppress the generation of metadata when this happens. Fixes <rdar://problem/9123036>. llvm-svn: 132171
