[RFC] Special case system apps for profile optimizations
If the OTA updates a system app which was previously preopted to a non-
preopted state the app might end up being verified at runtime. That's
because by default the apps are verify-profile but for preopted apps
there's no profile.
Do a hacky check to ensure that if we have no profiles (a reasonable
indication that before the OTA the app was preopted) system apps get
compiled with a non-profile filter (by default interpret-only).
Bug: 30032273
Test: Andreas "has verified that Calin's change to A/B works as expected
and promotes things like SystemUI to speed. From my side, that's
ready to be merged"
