[PATCH 14/20] s390: vlr uses instruction format VRR

This patch corrects the instruction format used for the S/390 vlr instruction. It updates the opcode definitions to specify that vlr V1,V2 uses the VRR_VV format, not the previously incorrectly assigned VRX_VV. The erroneous VRX_VV definition is removed from the opcode implementation.
