This commit changes the behavior of KT-59138 effectively declining it in 2.0.
However, we plan to implement KT-59138 behavior under a feature
flag in 2.0 (see KT-66447), and switch this feature on version 2.x.
Also, this commit implements the LC resolution about postponing
KT-57014 change. We don't have KT-57014 described behavior in 2.0 anymore.
However, we plan to implement a deprecation warning here, see KT-65578.
After this commit, 6 diagnostic tests become incorrectly broken:
- 5 tests from PurelyImplementedCollection group
- a test platformTypes/nullableTypeArgument.kt
This commit also breaks currently fixed-in-k2 KT-50134
(it is fixed again in the following commits),
as well as KT-58933 (it will remain not fixed till we enable KT-59138
behavior again).

It was decided to forbid such comparisons,
as we know how `===` works. Also, added some more
test cases, just for comparison.
Reusing the proper `canHaveSubtypes()`
from `TypeUtils` prevents a breaking change
in:
- `comparingTripleWithPair.kt`
- `comparisonOfGenericInterfaceWithGenericClass.kt`
But it does lead to warnings
(instead of errors) in
`incompatibleEnumEntryClasses.kt`, which is an
unrelated mistake that will be fixed in the next
commit.
The refactoring in `canHaveSubtypes()` is purely
cosmetic - otherwise reading these conditions is hard
(and they don't fit my screen vertically).

This fixes some cases where we infer some type variable inside one
of the branches to Nothing instead of the expected type because Nothing
appeared in some other branch.
Specifically, we add an equality instead of a subtype constraint during
completion of calls to synthetic functions for if/when, try and !!.
We don't do it when the call contains a (possibly nested) elvis or is
inside the RHS of an assignment.
Otherwise, we would prevent some smart-casts.
#KT-65882 Fixed
Check all members for `Visibility.Unknown`,
otherwise we miss them when they come
from supertypes. This is the reason why
the FP intellij build failed with a
cryptic stacktrace instead of a
human-readable diagnostic.
Also, do report the diagnostic at all
cases of `Visibilities.Unknown`. Turns
out, there are no "simple to reason
about" situations here :(
Also, an interesting detail:
`retrieveDirectOverriddenOf` returns an
empty list for intersection overrides.
But this doesn't seem to break anything...
Replacing `CANNOT_INFER_VISIBILITY`'s
type `KtDeclaration` with
`PsiNameIdentifierOwner` and the related
changes in `PositioningStrategies`
were needed to prevent an exception saying that
`PsiClassImpl` is not a subtype of
`KtDeclaration`.
As the result of the latest changes to stdlib, the muted test succeeds.
Thus "java.lang.AssertionError: Test contains MUTE_LL_FIR directive but
no errors was reported. Please remove directive".
It was decided to unmute the test for now until the compiler team
fixes the issue. See KT-65218
When a type annotated with @PurelyImplements (explicitly or implicitly)
inherited some methods from a java supertype and the purely implemented
Kotlin supertype, it was inconsistent which of the signatures the
intersection override would have (with or without flexible types).
This commit adds support for the enhancement of intersection overrides.
If one of the overridden methods has non-flexible types, the enhanced
method will have non-flexible types.
This fixes some false negative nullability type mismatches.
#KT-59921 Fixed
This fixes a bunch of missing overridden symbols in IR.
This is also required for fixing KT-59921 in the following commit
where we need to keep all overridden symbols of intersection overrides
so that we can enhance them properly.

In more details, we use either platform override checker (if we came
from platform) or the combined intersection scope override checker
at this place. Also this commit fixes various places around
JavaOverrideChecker, allowing to apply it in intersection override
checker properly:
- don't consider return types in this place
- apply JavaOverrideChecker if at least one candidate is from Java
- compare type primitivity closer to K1 logic
#KT-62554 Fixed
Partially fixes KT-63242
The inter-module interaction was partially supported, but the
DiagnosticCompilerTestFE10TestdataTestGenerated and
LFirPreresolvedReversedDiagnosticCompilerFE10TestDataTestGenerated were
failing. This is because the arguments of annotations were not fully
resolved in loadExperimentalitiesFromAnnotationTo function.

At the moment, SubclassOptInRequired is marked with the
ExperimentalSubclassOptIn annotation. However, it does not work
as expected due to a missing opt-in error. To use SubclassOptInRequired,
an explicit opt-in is necessary because SubclassOptInRequired is an
unstable feature now.
^KT-64739
Previously, if the parent class was in Java code and the subclass in
Kotlin, the opt-in usage error would not be reported for the subclass.
The problem was that the extractClassFromArgument function couldn't get
the class type from Java code. It was looking for a ConeClassLikeType,
but found a ConeFlexibleType instead.
#KT-60258 Fixed
While reporting a diagnostic there seems to be correct because the
parameter type is ConeErrorType, the former fact is a bug
in PCLA that should be fixed soon
Previously, error types on those implicit parameters were being lost.
Changed test data is only partly here
(only parts that are considered to be correct).
Other ones (new green-to-red changes) should belong to the next commit
and will be fixed soon (as a part of PCLA).
This diagnostic may be reported even without any compiler plugins (e.g.
for annotation named `Target` or `Deprecated`), so the old name
and message were quite confusing

This commit breaks two diagnostic tests:
- testSuspendJavaImplementationFromDifferentClass
- testSuspendJavaOverrides

There are many complications with the current design of passing data
from within in-place lambdas to surrounding code. Solving these
complications will involve more time to investigation than is available
within the K2 release. So we are disabling passing type statement
information from lambdas for the time being until more time can be
devoted to a more complete solution.

This commit solves a stub type inconsistency problem.
As a part of KT-59369 fix we decided (see commit 299d2799),
that ConeStubTypeForChainInference has a scope of Any,
so we can safely resolve only to equals/hashCode/toString.
However, later we can replace a stub type with some inferred type,
which can have its own equals/hashCode/toString implementation,
while the call still refers Any member.
In this situation FIR2IR decides that we are calling a fake override,
which is not true, in fact we are calling an overriding method.
This leads to a crash in Native backend.
To solve this situation, we provide an explicit cast of a dispatch
receiver with a stub type (ConeStubTypeForChainInference) to Any,
thus confirming directly we are calling Any method and nothing else.
