// Through various tests, it seems the compiler generates much better code by
// passing the opcode as a primitive datatype (as it can stick the value directly
// in a register rather than passing it via the stack). Unfortunately we have to
// create a temporary to be able to pull the various fields from the opcode, but
// the compiler is clever enough to optimiste this overhead away.
