* Convert to use LiveVariable analysis * Convert to use PHIElimination pass * Don't spill values which have just been reloaded (big win reducing spills) * Add experimental support for eliminating spills before TwoAddress instructions. It currently is broken so it is #ifdef'd out. * Use new "is terminator" flag on instructions instead of looking for branches and returns explicitly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@5219 91177308-0d34-0410-b5e6-96231b3b80d8
