Function instr_has_encoding_hint 

pub unsafe extern "C" fn instr_has_encoding_hint(
    instr: *mut instr_t,
    hint: dr_encoding_hint_type_t,
) -> bool_

Each instruction may store a hint for how the instruction should be encoded if redundant encodings are available. This presumes that the user knows that a redundant encoding is available. This routine returns whether the \p hint is set for \p instr.
