doc: -Wdelete-non-virtual-dtor supersedes -Wnon-virtual-dtor
The newer -Wdelete-non-virtual-dtor has no false positives and fewer
bugs. There is very little reason to use -Wnon-virtual-dtor instead.
gcc/ChangeLog:
* doc/invoke.texi (C++ Dialect Options): Recommend using
-Wdelete-non-virtual-dtor instead of -Wnon-virtual-dtor.
