  * remove old quadratic grin simplifier in favor of newer linear(ish) one. re-enable several grin optimizations.

Thu Aug 27 01:56:26 PDT 2009  John Meacham <john at repetae.net>
  * perform case return unboxing when on the simplifiers upwards pass to have it converge in fewer iterations

Thu Aug 27 03:43:36 PDT 2009  John Meacham <john at repetae.net>
  * add new grin optimizatons, case merging and getting rid of superfluous returns

Thu Aug 27 18:08:25 PDT 2009  John Meacham <john at repetae.net>
  * fix issue in return unboxing optimization that would sometimes re-create constants on the heap

  * remove old 'Store' grin operation in favor of the StoreNode and Demote basic ops

  * after node analysis, modify function bodies.

Fri Aug 28 02:47:36 PDT 2009  John Meacham <john at repetae.net>

Fri Aug 28 04:17:51 PDT 2009  John Meacham <john at repetae.net>
  * add unboxing of demotions

Fri Aug 28 07:29:43 PDT 2009  John Meacham <john at repetae.net>
