[binutils][aarch64] New sve_size_013 iclass.
Add sve_size_013 instruction class This new iclass handles instructions such as pmullb whose size specifier can only be encoded as 0, 1, or 3. include/ChangeLog: 2019-05-09 Matthew Malcomson <matthew.malcomson@arm.com> * opcode/aarch64.h (enum aarch64_insn_class): Add sve_size_013 iclass. opcodes/ChangeLog: 2019-05-09 Matthew Malcomson <matthew.malcomson@arm.com> * aarch64-asm.c (aarch64_encode_variant_using_iclass): Handle sve_size_013 iclass encode. * aarch64-dis.c (aarch64_decode_variant_using_iclass): Handle sve_size_013 iclass decode.
