Implement AArch64 post-index vector load/store multiple N-element structure class SIMD(lselem-post).
Including following 14 instructions:
4 ld1 insts: post-index load multiple 1-element structure to sequential 1/2/3/4 registers.
ld2/ld3/ld4: post-index load multiple N-element structure to sequential N registers (N=2,3,4).
4 st1 insts: post-index store multiple 1-element structure from sequential 1/2/3/4 registers.
st2/st3/st4: post-index store multiple N-element structure from sequential N registers (N = 2,3,4).
