The previous implementation had issues with
locks, publication and performance
Also, this change fixed a problem with mixed cycle inheritance

This commit is intended to avoid the second resolve of delegate when
we need to consider provideDelegate() possibility in inference.
Also here we provide correct completion of synthetic calls during
delegate inference.
#KT-58013 Fixed
This changes the logic so that Foo<T> is reported no matter if T is
reified or not. Even for Array<reified T> to align K2 with K1 logic.
#KT-55903 Fixed
For explanation, see nestedPartiallyResolvedCallsSimple.k
The problem was caused by "select" variable is being leaked to the
inference session of delegate while it should not happen because
it doesn't belong to the common system of `KotlinVal { ..` call,
as we complete it with fixing `E` variable during completion
for `A(select(null, fun(): Int { return 1 }))`.
The root of the problem is that we were adding all the partial
nested calls to the session, while in fact we only need there
the top-level one.

Before this commit, for property candidates in K2 their types wasn't
inferred/susbtituted properly.
So, when candidate for fooBar.liveLoaded.invoke() was created,
the type of `fooBar.liveLoaded` was just X type parameter for which
there is no any `bar()` functions in its member scope.
While proposed semantics is a bit different from K1, where
both property and invoke candidates are united into common system,
it doesn't contradict to the specification (https://kotlinlang.org/spec/overload-resolution.html#callables-and-invoke-convention)
which says explicitly that invoke-convention should be desugared as
`r.foo.invoke()`, thus `r.foo` should be completed independently.
Also, this strategy supports some reasonable use-cases like KT-58259
while it's still a breaking change but for more artificial-looking
situations (see KT-58260) and should be passed through
the language committee.
The changes in stubTypeReceiverRestriction* tests looks consistent
because of how `genericLambda` now works
(with full completion of property call).
NB: The code is going to be red once KT-54667 is fixed and also there's
already similar diagnostic in K1 (INFERRED_INTO_DECLARED_UPPER_BOUNDS)

This fixes a false positive TYPE_PARAMETER_IS_NOT_AN_EXPRESSION when
a type parameter and some member, static or companion declaration have
the same name and referred to inside a class.

when source for compiled fir elements is set, it leaks e.g. to diagnostics,
which is then filtered

There's a heuristic for approximation of a captured type that once
it has non-trivial lower bound (other than Nothing), it's worth
approximating it to sub-type even while the containing
top-level type is being approximated to super-type.
And that sounds reasonable in case the lower bound is indeed non-trivial,
but that's not the case because nullability here comes from
the nullability of captured type position.
So, the fix is basically not to treat such approximations as non-trivial.
And while that seems to be a bit of a change in the language semantics,
it still looks reasonable (see other changes in test data and KT-58087)

While plainly repeating K1 behavior might be a dumb solution,
but inventing another one might be quite complicated
because we need to stop fixing variables into Nothing in many cases,
but probably not in all of them (see KT-58232).

This fixes a false positive resolution error for callable references
to functions with a type parameter that's annotated with
@OnlyInputTypes.
#KT-57994 Fixed
This is a partial revert of 949a39b80f. In the end it turned out not
necessary to prohibit this case (and perform a breaking change), because
JVM backend was fixed to generate it correctly in d73d3c46e2.

The change is needed for the parallel resolution (^KT-55750), so we can resolve the declaration
under a lock that is specific to this declaration.
Previously, if LL FIR was resolving some FirClass, LL FIR resolved all its children too, and it had no control over what parts of the FIR tree were modified.
The same applied to the designation path, sometimes the classes on the designation path
might be unexpectedly (and without lock) modified.
This commit introduces LLFirResolveTarget, which specifies which exact declarations should be resolved during the lazy resolution of the declaration.
All elements outside the declarations specified for resolve in LLFirResolveTarget, should not be modified.
The logic of lazy transformers is the following:
- Go to target declaration collecting all scopes from the file and containing classes
- Resolve only declarations that are specified by the LLFirResolveTarget, performing the resolve under a separate lock for each declaration

Enum entries can be used as types in Kotlin (even it's a compilation error)
To use the classifier as a type, we need to find if it's hidden or not.
The deprecations for classes are calculated on COMPILER_REQUIRED_ANNOTATION phase, and that's okay as it goes before the TYPES phase.
For enum entries, the deprecations are calculated on TYPES phase which goes on TYPES phase.
This is incorrect as we cannot jump from lower phase to upper phase
The hack ignores such deprecation search for enum entires.

The problem appeared because not all of the `realOverridden` have been
collected because inside AbstractSerializableListDecorator some of the
scopes returned the same instance as direct overridden and after that
overridden tree traversal stopped without detecting real overrides.
Thus, the modality of intersection for
AbstractSerializableListDecorator::size and MutableSet::size
was incorrectly computed to ABSTRACT
The similar thing is already done at the place where we're obtaining
all overrides.

This commit fixes an inconsistency between
FirUnsupportedSyntheticCallableReferenceChecker and
UnsupportedSyntheticCallableReferenceChecker
In K1 such properties were not considered synthetic and are called
JavaPropertyDescriptor. That's why we need to do an additional check in
K2 checker, while in K1 we didn't need to do it
Also see the previous commit for more related tests that already was
green without this fix but are related to KT-58061 problem
Review: https://jetbrains.team/p/kt/reviews/9677
I'm going to fix KT-58061 in the next commit. Firstly, let's cover
FirUnsupportedSyntheticCallableReferenceChecker with more tests that
already pass, but are related to KT-58061 problem.
Other related tests:
- testGenericJavaProperty
- testFunInterfaceConstructorReference
Meta issue: KT-8575
Review: https://jetbrains.team/p/kt/reviews/9595
UnsupportedSyntheticCallableReferenceChecker only existed for K1,
because we wanted to release the feature for 1.9 and the feature should
have been working for K2 unconditionally. But since, we're postponing
the release until 2.1, we also need to port the checker from K1 to K2
The issue is that during binding fake overrides, the compiler doesn't
differ setters from its properties, so the compiler uses the same
visibility for setter and entire property.
Changing logic at the binding stage can cause some unpredictable consequences so
the fix is to do this differentiation right at the reporting stage
