We already have two. First is X86EMUL_ (not enum but close) for
more or less internal emulator use. Second is EMULATE_* for users of
emulate_instruction() now you want one more enum for communication
between emulate_instruction() and x86_emulate_insn(). Lost in enums.
emulate_instruction() and x86_emulate_insn() are tightly coupled right
now should we define formal interface between them? May be comment will
be enough?
