Or you could wait a bit[1] and have LLVM do that for you, assuming 
you're willing to run LLVM bytecode. And considering it's LLVM, you 
could probably hack it to periodically dump the optimized code. So you'd 
optimize your application by fooling around with it for a couple hours.

[1] "A bit" may be as long as a decade. I dunno.
