make -freg-struct-return visibly a negative alias of -fpcc-struct-return
The fact that both options accept negative forms suggests that maybe
they aren't negative forms of each other. They are, but that isn't
clear even by examining common.opt. Use NegativeAlias to make it
abundantly clear.
for gcc/ChangeLog
* common.opt (freg-struct-return): Make it explicitly
fpcc-struct-return's NegativeAlias.
