Start rewroking a subpiece of the profitability heuristic to be phrased in terms of liveness instead of as a horrible hack. :) In pratice, this doesn't change the generated code for either 255.vortex or 403.gcc, but it could cause minor code changes in theory. This is framework for coming changes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60082 91177308-0d34-0410-b5e6-96231b3b80d8
