The CL 249758 added `FMOVQ $vcon, Vd` instruction and assembler used 128-bit simd literal-loading to load `$vcon` from pool into 128-bit vector register `Vd`. Because Go does not have 128-bit integers for now, the assembler will report an error of `immediate out of range` when assembleing `FMOVQ $0x123456789abcdef0123456789abcdef, V0` instruction. This patch lets 128-bit integers take two 64-bit operands, for the high and low parts separately and adds `VMOVQ $hi, $lo, Vd` instruction to move `$hi<<64+$lo' into 128-bit register `Vd`. In addition, this patch renames `FMOVQ/FMOVD/FMOVS` ops to 'VMOVQ/VMOVD/VMOVS' and uses them to move 128-bit, 64-bit and 32-bit constants into vector registers, respectively Update the go doc.
