Three-byte opcodes from the 0F3Ah area all have an immediate byte which is usually unsigned. Clarify in the helper code that it is unsigned; the new decoder treats immediates as signed by default, and seeing an intN_t in the prototype might give the wrong impression that one can use decode->immediate directly.
