This PR reimplements DestinationPropagation as a problem of merging live-ranges of locals. We merge locals that have disjoint live-ranges. This allows merging several locals in the same round by updating live range information. Live ranges are mainly computed using the `MaybeLiveLocals` analysis. The subtlety is that we split each statement and terminator in 2 positions. The first position is the regular statement. The second position is a shadow, which is always more live. It encodes partial writes and dead writes as a local being live for half a statement. This half statement ensures that writes conflict with another local's writes and regular liveness. r? `@Amanieu` Reimplement DestinationPropagation according to live ranges. 2025-09-07T16:24:46+00:00 Camille GILLOT gillot.camille@gmail.com 2025-07-02T08:36:22+00:00 urn:sha1:9b8a719ae48db491a5f18d52fdbb802508bf75a5
