Fix earlier commit missing patch review changes

Browse Source 
Somehow I lost my fixes based on Segher's review of the p10
logical-logical fusion patch. This commit adds the changes that
should have been there before. Bootstrap/regtest passed.

gcc/ChangeLog:

	* config/rs6000/genfusion.pl (gen_2logical): Add missing
	fixes based on patch review.
	* config/rs6000/fusion.md: Regenerate file.
