This fixes a fallout that actually goes back to 5.0 but went unnoticed.
The costs for movt and movrt type of insns were not correctly reported
and ifcvt thus made some bad choices for SH. A new cset_zero pattern
variant is also required to fix the matching for some recent changes
in the middle end.
