Make parcelize work consistently with
`FirOverrideChecker`.
Actually, there is a philosophical question about
what to do when a plugin generates a class
in a new package, and this class is red code
(for instance, doesn't implement an abstract
member from a supertype). There's no source
to report such an error, but we probably do
want to run checkers to avoid trying to
compile red code to binaries (because it may
crash in backend, or it may silently work).
Introduce an extension method to retrieve the set of applicable targets
for an annotation, given the annotation class's symbol.
This extension on `KtSymbolInfoProvider` causes a large amount of churn
in test data files, so this change starts off by introducing the
property and always making it return null. A future change will
introduce the actual behavior change, and will include the testdata
changes for the few tests that actually return useful data for this
property.
