operator!= fixes for C++-20
Without these changes, more recent versions of Clang will start to emit diagnostics: src/abg-ir.cc:15407:13: error: member 'operator!=' found in multiple base classes of different types 15407 | return *l == *r; | ^ src/abg-ir.cc:14123:12: note: member found by ambiguous name lookup 14123 | type_base::operator!=(const type_base& other) const | ^ src/abg-ir.cc:5162:12: note: member found by ambiguous name lookup 5162 | decl_base::operator!=(const decl_base& other) const | ^ This fix was contributed by Ilya Biryukov. * include/abg-ir.h (qualified_typedef): Add definition of operator!=. (pointer_type_def): Likewise. (reference_type_def): Likewise. (class_or_union): Likewise.
