Currently liveness only produces a stack map index at each safe point, so the information is summarized in a map[*ssa.Value]int. We're about to have both a stack map index and a register map index, so replace the int with a LivenessIndex type we can extend, and replace the map with a LivenessMap that we can also change more easily in the future. This also gives us an easy hook for defining the value that means "not a safe point". Passes toolstash -cmp. For #24543.
