The MIPS documentation describes a -mmad (-mno-mad) flag, but it is incorrectly
implemented as -mad (-mno-ad) instead. This patch changes the implementation
to match the documentation. This means that users who are currently using the
-mad or -mno-ad flags would have to change. If we want we could leave -mad and
-mno-ad as aliases for -mmad and -mno-ad but I don't think that is necessary.
If someone does think we should do allow -mad, please let me know.
OK to checkin?

OK, thanks. Looks like I introduced this in the TARGET_OPTINS ->
.opt-file conversion.
