Change to CompilationStateBuilder to prevent recursive invalidation on changed units.

Previously, changing any unit would not only force that unit to be recompiled, but we would then transitively invalidate any units depending on that unit.  So changing one file could result in hundreds of invalidated units.

With this change, we only recompile referrers when a unit changes *structurally*.  That is, when its API changes.  This means that a simple code change to a unit will only recompile that unit, and API changes generally won't go beyond direct referrers.
