What if more than one instruction worth of C were chained together 
before being compiled? Would that make more optimisable code? Could 
this even be done at runtime? Translation time would be greatly 
increased of course, making caching even more important.

Is this technically feasible? Or would my time be better spent 
writing a hand optimised code translator? ;)
