Sorry, going it over it again before committing, I spotted a couple of thingsā¦

Also, I don't think we can require csplit. genemit itself is quite fast, so it would probably be simpler to run it multiple times, passing a new command-line parameter to say which output file we want. In other words, rather than generate a monolithic insn-emit.c and then split it later, we should just generate the separate insn-emit.cs directly. Thanks, Richard
