When emitting a method definition in debug info, the compiler should also emit the method's declaration, because LLVM LTO can't unify type definitions when a child DIE is a full subprogram definition. This is already the behavior for standard methods, this patch implements the same behavior for witness and objc methods as well. rdar://123334375
