Add an experimental -early-live-intervals option.
This option runs LiveIntervals before TwoAddressInstructionPass which will eventually learn to exploit and update the analysis. Eventually, LiveIntervals will run before PHIElimination, and we can get rid of LiveVariables. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161270 91177308-0d34-0410-b5e6-96231b3b80d8
