cmd/asm: fix RLDCR const1,reg,const2,reg on ppc64
The extended opcode field (XO) is generated incorrectly. OPVCC
assumes an X-form like layout for the XO field. MD-form insns
also have an XO field, but it is both smaller and in a different
bit position.
This hasn't been noticed since const1 == 0 matches as a register
argument instead of a constant, thus it is unlikely anyone has
attempted to assemble this instruction with a non-zero shift
argument.
Likewise, update all other MD-form instructions using OPVCC
to use the new OPMD function.
