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

You should not use leading underscore. It is reserved by implementer
of compilers and libraries.
