AArch64: Refactor err_type.
Previously the ERR_ values were defined as different constants, to make this a
bit more type safe and so they can be more easily re-used I'm changing them into
an actual enum and updating any usages.
include/
* opcode/aarch64.h (enum err_type): New.
(aarch64_decode_insn): Use it.
opcodes/
* aarch64-dis.c (ERR_OK, ERR_UND, ERR_UNP, ERR_NYI): Remove.
(aarch64_decode_insn, print_insn_aarch64_word): Use err_type.
