I'm not too thrilled about the code that checks whether implicit copy assignment is legal; we have very similar code in elsewhere (e.g., Sema::DefineImplicitOverloadedAssign), and it would be unfortunate to have to keep these in sync... also, if we have to do this for copy-assignment, wouldn't we have to do this for all of the implicit special member functions?
