Yi Kong 19a29ac0d0 Port memory barriers intrinsics to AArch64
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.

Requires LLVM r213247.

Tim Northover a2ee433c8d ARM64: initial clang support commit.
This adds Clang support for the ARM64 backend. There are definitely
still some rough edges, so please bring up any issues you see with
this patch.

As with the LLVM commit though, we think it'll be more useful for
merging with AArch64 from within the tree.
