Remove magic numbers in m68k-dis.c:print_insn_arg
When I inspect the return values of disassmblers, I happen to see
various -1/-2/-3 magic numbers are used in m68k-dis.c. This patch
is to replace them with enum.
-1 and -2 is "clearly documented" in print_ins_arg's comments, but
-3 isn't. In fact, -3 is returned when FETCH_DATA returns false,
which means memory error (because fetch_data return 0 on memory
error). So I name enum PRINT_INSN_ARG_MEMORY_ERROR for -3.
This patch is a refactor patch, doesn't affect any functionality.
opcodes:
