Fix a significant recent(?) regression. StackSlotColoring no longer did anything
because LiveStackAnalysis was not preserved by VirtRegWriter. This caused big stack usage regression in some cases. rdar://12340383 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@164408 91177308-0d34-0410-b5e6-96231b3b80d8
