Series [committed] Remove duplicate logical<mode>3_sn pattern | expand

Commit Message

Jeff Law July 4, 2018, 2:22 a.m. UTC 
After consolidating HI and SI mode patterns for logical bit operators,
the remaining patterns "logical<mode>3_sn" "logical<mode>3" are in
effect identical.

This patch deletes logical<mode>3_sn.

This (not surprisingly) makes no difference in the generated code :-)

* config/h8300/h8300.md (logical<mode>3_sn, logical<mode>3): Merge
	into a single pattern.
