You rewrote part of coalesce_spill_slots in the change for PR37488 and 
inverted the condition of the first IF within the "j" loop and replaced 
"<" with ">" instead of ">=", right?

The change for PR37488 hasn't been reviewed for the trunk yet, which 
explains why we were only seeing this failure on HJ's branch.    I've 
looked at the changes for 37488 a couple times, but haven't wrapped my 
head around them completely. 

I'm going to consider this patch a revision to the changes for pr37488 
and handle them together.  I'll try to finish reviewing the changes for 
37488 today.
