1. When an annotation has multiple targets, the priority goes like this:
constructor parameter (if applicable) -> property -> backing field.
2. The argument to `kotlin.annotation.Target` is a vararg, so that
should be handled as well.
3. `AnnotationTarget.VALUE_PARAMETER` allows receivers, constructor
parameters, and setter parameters, while `AnnotationTarget.FIELD` allows
both backing fields and delegates.
Known issue: java.lang.annotation.Target is not remapped to the Kotlin
equivalent, so things are still broken for pure Java annotations.
In the old backend, targets are generated in the order of their
declaration in the ElementType enum, see AnnotationCodegen.java:306
(EnumSet guarantees such iteration ordering).
This has no effect other than reducing non-essential differences when
comparing ABI of JVM vs JVM_IR.
- Allow participating subtypes of functional types in conversions
- Fix several subtle inconsistencies
- Place logic about conversions at one place
Now conversions operations have two stages: before usual subtyping
check and after one. This is needed to support conversions of
subtypes (of functional types, for example). First, the compiler
checks if it possible to resolve an argument without conversion and
only then it tries to perform conversion.
Note that it'd be incorrect to perform conversion eagerly as it can
change resolve (Runnable & () -> Unit <: KRunnable), plus we can't
guess whether conversion is needed at all as it's important not to
look into supertypes if resolution doesn't actually needed it

Before this commit we considered !isOverride as a sign that
function / field / accessor has no overridden symbols.
However, it's false for deserialized, because isOverride
is always false there.
This commit fixes 68 BB tests but breaks 25 BB tests (not yet muted)
Without this commit, JVM name mapping logic in BE does not work for FIR,
because FIR cannot use old BuiltInsPackageFragmentImpl descriptor.
In this commit we add our own implementation thus fixing
a pack of FIR black box tests.
