Actually optimize in PACK-TN

We used to track location usage information, but never use it to
determine which register to use.  I'm not actually convinced that
this change improves the quality of the code we generate, but it
can't hurt for PACK-TN to actually do what it says it does: usage-
guided packing can always be disabled if it's not useful.
