Dynamically determine the CostPerUse value in the register allocator.
I dont know the history behind CostPerUse word so I may be missing the
background associated with it. It seems that it's misnomer for what it is
intended. At first sight, the word indicates that the cost is a function of
uses of the register - more the uses more the cost. How do we want to
define the value of CostPerUse. Should it be a function of uses? or just
the target?
