Tim Keith 2fb1c16e94 [flang] Clean up; fix assert and crashes ... This is the result of running `f18 -fdebug-resolve-names` on a bunch of Fortran source and fixing the resulting assertion errors and segmentation faults. Most of the problems were with encountering attributes, array specs, or declaration type specs when we weren't prepared to handle them. Those were fixed by adding calls to {Begin,End}DeclTypeSpec and {Begin,End}Decl when encountering certain nodes, though the real work for those nodes is still to be done. Extract some common functionality into PostAttrSpec and CheckUseError. Add missing XOR to GenericSpec.
