Simple optimization pass that splits independent uses of each pseudo,
increasing effectiveness of other optimizations.  The optimization can
serve as an example of use for the dataflow module.

TODO
 - We may use profile information and ignore infrequent use for the
   purpose of web unifying, inserting the compensation code later to
   implement full induction variable expansion for loops (currently
   we expand only if the induction variable is dead afterward, which
   is often the case).
