Basically, this bug boiled down to calling replaceUsesOfWith on a constant,
which changed it's shape in an illegal way.  This pass now goes through all
of the trouble neccesary to do the replacement on constants.

This fixes a number of FP precision problems, making the output of the
power benchmark closer to the right answer.

Unfortunately, this only addresses FP constants used directly in functions.
Constants referred to by global constants (such as an array of FP values)
aren't helped by this.  Until this happens power won't work.
