Fix operand order to subf for p10 fusion.

This certainly causes a bootstrap miscompare, and might also be
responsible for PR/100820. The operands to subf were reversed
in the logical-add/sub fusion patterns, and I screwed up my
bootstrap test which is how it ended up getting committed.

gcc/ChangeLog

* config/rs6000/genfusion.pl (gen_logical_addsubf): Fix input
order to subf instruction.
* config/rs6000/fusion.md: Regenerate.
