Modify the comparison optimizations in the peephole optimizer to update the
...
iterator when an optimization took place. This allows us to do more insane
things with the code than just remove an instruction or two.

Merge the OptimizeExts and OptimizeCmps passes into one PeepholeOptimizer
...
pass. This pass should expand with all of the small, fine-grained optimization
passes to reduce compile time and increase happiment.
