cmd/asm: fix rlwnm reg,reg,const,reg encoding on ppc64
The wrong value for the first reg parameter was selected.
Likewise the wrong opcode was selected. This should match
rlwnm (rrr type), not rlwinm (irr type).
Similarly, fix the optab matching rules so clrlslwi does
not match reg,reg,const,reg arguments. This is not a valid
operand combination for clrlslwi.
Fixes #42368
