Using this emit function implicitly creates three copies, which is pointlessly inefficient. 1. Code creates the original instruction. 2. Calling emit(fs_inst) copies it into the function. 3. It then allocates a new fs_inst and copies it into that. The second could be eliminated by changing the signature to fs_inst(const fs_inst &) but that wouldn't eliminate the third. Making callers heap allocate the instruction and call emit(fs_inst *) allows us to just use the original one, with no extra copies, and isn't much more of a burden.
