Add a comment about overlapping PPC frame offsets
I don't think that it is otherwise clear how the overlapping offsets are processed into distinct spill slots. Comment that this is done in processFunctionBeforeFrameFinalized. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177094 91177308-0d34-0410-b5e6-96231b3b80d8
