Sounds like you're looking for a Sufficiently Smart Compiler[0]. James Hague has a good piece on why this might not be so desirable[1].
One of the reasons I'm fond of Python is that, while there is a tradeoff between flexibility and performance, it gives you the means to sacrifice flexibility to aid you in improving performance -- once you've identified what (if any) actual performance bottlenecks you face.
