Add first version of the sorting benchmark.
Duplicate sorting benchmark to start hacking ti
Hacking on sorting.  Add a few results
sorting: Flag the places where IVar writes will go
sorting: Duplicate the outofplace version to begin work on the ivar version
sorting: switch over to 64 bit elements
sorting: laying groundwork for ivar version
sorting: Eek, it looks like there's a new 2X slowdown in this rev, but WHERE did it come from?  Not the calloc it seems.
Orphaned changes from Tim.  Dunno what is in here.
sorting: Notes about bad performance with concurrent cilk.  Need to switch cilkmerge to take ivars.  There's a hack in there now.
Set things up for cilkmerge to use ivars... but when I pull the switch things break
sorting: first attempt to switch over to ivars.  Currently getting bad answers.  Must have missed a spot.
Fix to previous.  It was a copy paste bug.
write in some results.  Also, make the outofplace version use calloc rather than malloc by default.
overhauling the cilkrts to use the ptr tags instead of a paused stack
