[binutils][aarch64] New sve_size_tsz_bhs iclass.
Add sve_size_tsz_bhs iclass needed for sqxtnb and similar instructions. This iclass encodes one of three variants by the most significant bit set in a 3-bit value where only one bit may be set. include/ChangeLog: 2019-05-09 Matthew Malcomson <matthew.malcomson@arm.com> * opcode/aarch64.h (enum aarch64_insn_class): Add sve_size_tsz_bhs iclass. opcodes/ChangeLog: 2019-05-09 Matthew Malcomson <matthew.malcomson@arm.com> * aarch64-asm.c (aarch64_encode_variant_using_iclass): Handle sve_size_tsz_bhs iclass encode. * aarch64-dis.c (aarch64_decode_variant_using_iclass): Handle sve_size_tsz_bhs iclass decode.
