Both the new and old incremental compilation (IC) analysis rely on
Kotlin class metadata to detect a change.
However, Kotlin metadata currently doesn't contain info about
annotations (KT-57919), so the IC will not be able to detect a change
to them.
With this commit, we'll fix the new IC such that it can detect a change
to class annotations by not relying only on metadata.
We currently scope this fix to the new IC (cross-module analysis) first.
We'll fix this issue for within-module analysis later.
Performance: There seems to be no performance impact from this change.
Snapshotting the 400MB ideaIC-2022.1.4/app.jar takes 4.1s before and
after this change.
