Use "final" and "override" directly, rather than via macros

As of GCC 11 onwards we have required a C++11 compiler, such as GCC 4.8
or later.  On the assumption that any such compiler correctly implements
"final" and "override", this patch updates the source tree to stop using
the FINAL and OVERRIDE macros from ansidecl.h, in favor of simply using
"final" and "override" directly.
