Summary: The fact that phis are identifiers rather than places is unfortunate in a few cases. In some later analyses, we might wish to know whether a phi is reactive, but we don't have an easy way to do that currently. Most of the changes here is just replacing phi.id with phi.place.identifier and such. Interesting bits are EnterSSA (several functions now take places rather than identifiers, and InferReactivePlaces now needs to mark places as reactive explicitly. [ghstack-poisoned]

There was a problem hiding this comment.
awesome! would be nice to remove markReactiveIdentifier if possible (fine for a follow-up)
