[PATCH][AArch64] Neon scalar x indexed element and scalar copy implementation

[Jiangning Liu]

Hi Ana,

MCHammer can pass SISD by element, but failed on assemble action of SISD
copy.

FAILED[0101 1110 0000 0001 0000 0100 0000 0000, 0x5e010400]: Should not be
undefined (MOV      b0,v0.B[0])
FAILED[0101 1110 0000 0001 0000 0100 0000 0001, 0x5e010401]: Should not be
undefined (MOV      b1,v0.B[0])

$ echo "MOV b0,v0.B[0]" | ~/llvm/build/bin/llvm-mc -triple=aarch64
-mattr=+neon -show-encoding -assemble -show-inst
.text
<stdin>:1:5: error: invalid operand for instruction
MOV b0,v0.B[0]
    ^

Thanks,
-Jiangning
