- This optimization applied to LL FIR can be extended to K2 as a whole.
Likely, there won't be any performance benefits in CLI runs, but it's
still better to avoid useless symbol providers.
- Dependency symbol providers contained a lot of useless
`FirExtensionSyntheticFunctionInterfaceProvider`s, because such a
provider only generates function classes from compiler plugins. If
there aren't any such `FunctionTypeKind`s in the session, there is no
need to even add the provider.
- `FirExtensionSyntheticFunctionInterfaceProvider`s that are added to
the list of dependency providers despite this optimization will now be
combined in `LLFirCombinedSyntheticFunctionSymbolProvider`. It checks
`ClassId` heuristics once, which is more efficient than checking them
in every provider separately.
- Similar to the implementation of `isNameForFunctionClass` in
`FirSymbolProvider`, `FirSyntheticFunctionInterfaceProvider` benefits
from checking the `ClassId` for a digit before accessing its class
cache.
Basically, this commit reworks eraseToUpperBound* stuff
Instead of a bunch of vague flags, we introduce two modes
(rawTypes/intersection emptiness checker) which defined those flags.
Also, it makes choosing `eraseArgumentsDeeply` option always because
that how it works in K1 and also use invariant projection inside
`eraseArgumentsDeeply` for raw types for the same reason.

so the check is functionally the same as in K1.
#KT-57064 fixed
#KT-57065 fixed
One of the tests introduced here (javaMappedCtors) revealed an
additional issue, filed as KT-57368
The idea of the fix is just unwrapping flexible version of type alias,
before creating a not-nullable version for safe-call subject.
Otherwise, it was remained to be JsExpressionResult after applying
makeConeTypeDefinitelyNotNullOrNotNull (and the type is still nullable)
^KT-57190 Fixed
During implicit body resolve phase, we can encounter a reference to a
not yet resolved Kotlin class that inherits a synthetic property from a
Java class. In that case, resolve the return type in
FirSyntheticPropertiesScope.
#KT-57166 Fixed
with dedicated opt-in language feature and special
annotation or module capability.
Not intended for a general use, solves specific K/N
scenario with interop libs.
#KT-55902 fixed
In that case, when loading Java, we just remember the name of `@Nonnull`
argument (javax.annotation.meta.When), and then use it during enhancement
^KT-56656 Fixed
The basic idea is that during deserialization/loading compiled
Java classes, there might be some of the dependencies absent that
are referenced from enum arguments in annotations.
Such situation is not considered as totally ill-formed, thus supporting
it, allowing to read the names of mentioned in the annotation argument
might be useful for Java enhancement
^KT-56656 In Progress
