EmitTargetMetadata passed to emitTargetMD a null pointer as returned from GetGlobalValue, for an unused inline function which has been removed from the module at that point. A FIXME in CodeGenModule.cpp commented that the calling code in EmitTargetMetadata should be moved into the one target that needs it (XCore). A review comment agreed. So the calling loop has been moved into the XCore subclass. The check for null is done in that loop. Differential Revision: https://reviews.llvm.org/D77068
