arm64: insn: Add BIT(23) to {load,store}_ex's mask
We are planning to add load-acquire (LDAR{,B,H}) and store-release
(STLR{,B,H}) instructions to insn.{c,h}; add BIT(23) to mask of load_ex
and store_ex to prevent aarch64_insn_is_{load,store}_ex() from returning
false-positives for load-acquire and store-release instructions.
