[PATCH] Port memory barriers intrinsics to AArch64

[Yi Kong]

Hi rengolin, t.p.northover, compnerd,

Memory barrier __builtin_arm_[dmb, dsb, isb] intrinsics are required to implement their corresponding ACLE and MSVC intrinsics.

This patch ports ARM dmb, dsb, isb intrinsic to AArch64. It relies on D4516.
