Revised statistics:
85 inner loop spills sunk
341 inner loop spills remaining
1162 inner loop spills that were candidates for sinking
ended up completely register allocated
119 inner loop spills could have been sunk were used in
"shuffling" at the bottom of the loop.
1 inner loop spill not sunk because the register assigned
changed between def and exit,
Understanding how to make an inner loop definition not be
a candidate for from-memory shuffling (to force the shuffle
code to choose some other value) should pick up some of the
119 other spills disqualified for this reason.
Modified the stats printing based on feedback from Austin.
