target/ppc: Implement Vector Insert from VSR using GPR index insns
Implements the following PowerISA v3.1 instructions:
vinsbvlx: Vector Insert Byte from VSR using GPR-specified Left-Index
vinshvlx: Vector Insert Halfword from VSR using GPR-specified
Left-Index
vinswvlx: Vector Insert Word from VSR using GPR-specified Left-Index
vinsbvrx: Vector Insert Byte from VSR using GPR-specified Right-Index
vinshvrx: Vector Insert Halfword from VSR using GPR-specified
Right-Index
vinswvrx: Vector Insert Word from VSR using GPR-specified Right-Index
