| | | | | | | | | | All registers created during splitting or spilling are assigned to the same stack slot as the parent register. When splitting or rematting, we may not spill at all. In that case the stack slot is still assigned, but it will be dead. llvm-svn: 116546

splitting or spillling, and to help with rematerialization. Use LiveRangeEdit in InlineSpiller and SplitKit. This will eventually make it possible to share remat code between InlineSpiller and SplitKit. llvm-svn: 116543
