target/ppc: Implement Vector Extract Double to VSR using GPR index insns
Implement the following PowerISA v3.1 instructions:
vextdubvlx: Vector Extract Double Unsigned Byte to VSR using
GPR-specified Left-Index
vextduhvlx: Vector Extract Double Unsigned Halfword to VSR using
GPR-specified Left-Index
vextduwvlx: Vector Extract Double Unsigned Word to VSR using
GPR-specified Left-Index
vextddvlx: Vector Extract Double Doubleword to VSR using
GPR-specified Left-Index
vextdubvrx: Vector Extract Double Unsigned Byte to VSR using
GPR-specified Right-Index
vextduhvrx: Vector Extract Double Unsigned Halfword to VSR using
GPR-specified Right-Index
vextduwvrx: Vector Extract Double Unsigned Word to VSR using
GPR-specified Right-Index
vextddvrx: Vector Extract Double Doubleword to VSR using
GPR-specified Right-Index
