Subject: [PATCH] Update base for Update on "[compiler] Add nullable abstract
 value field to places and phis"

Test Plan:
This PR starts the process of tracking abstract values (and therefore value kinds) on a per-place basis and persisting that into the place data structure. Here, we simply add a nullable field for abstract values to all places and phis--it will be populated in the next PR.
