target/ppc: implement lxvr[bhwd]/stxvr[bhwd]x
Implement the following PowerISA v3.1 instuctions:
lxvrbx: Load VSX Vector Rightmost Byte Indexed X-form
lxvrhx: Load VSX Vector Rightmost Halfword Indexed X-form
lxvrwx: Load VSX Vector Rightmost Word Indexed X-form
lxvrdx: Load VSX Vector Rightmost Doubleword Indexed X-form
stxvrbx: Store VSX Vector Rightmost Byte Indexed X-form
stxvrhx: Store VSX Vector Rightmost Halfword Indexed X-form
stxvrwx: Store VSX Vector Rightmost Word Indexed X-form
stxvrdx: Store VSX Vector Rightmost Doubleword Indexed X-form
