There was a problem hiding this comment.
Trust that all previous property loads were added correctly. If a property load chain ever spans multiple blocks, this is technically the correct behavior

Rename for clarity:
- `CollectHoistablePropertyLoads:Tree` -> `CollectHoistablePropertyLoads:PropertyPathRegistry`
- `getPropertyLoadNode` -> `getOrCreateProperty`
- `getOrCreateRoot` -> `getOrCreateIdentifier`
- `PropertyLoadNode` -> `PropertyPathNode`
Refactor to CFG joining logic for `CollectHoistablePropertyLoads`. We now write to the same set of inferredNonNullObjects when traversing from entry and exit blocks. This is more correct, as non-nulls inferred from a forward traversal should be included when computing the backward traversal (and vice versa). This fix is needed by an edge case in #31036
Added invariant into fixed-point iteration to terminate (instead of infinite looping).
