I don't really know which exact commit fixed this test, but there was
a problem with return types of delegated members. Before my changes
delegated `override fun foo(x: Int)` in `actual class E` had error
return type and now it has correct type `Int`
^KT-61039 Fixed
KT-59739 is now open for K1 (but fixed in K2)
Review: https://jetbrains.team/p/kt/reviews/11867/timeline
This partially reverts commit 4f3ecedbca.
Only K1 part is reverted.
Motivation for revert: KT-59739 cannot be properly fixed in K1 because
of the bug it causes - KT-61039
We just accepted that we will have one more "green in K1 -> red in K2"

Reduce complexity by reusing "expect-actual matcher" (namely
`AbstractExpectActualCompatibilityChecker.getCallablesCompatibility`)
The current solution has worse algorithmic complexity. Previously it was
O(n) in the best case, where `n` is a number of members. Now, it's
O(m^2), where `m` is number of members in one overload group. But we
prefer to have worse complexity but reuse expect-actual matcher, number
of elements in one overload group shall not be big on real world
examples.
The previous logic was non-trivial because it compared types with with
double comparison in `equals`.
Motivation: the discovered false negative in test
changeModalityFromAbstractToOpenInOverride.kt
Unfortunately, it can't be fixed in K1, so we will just live with that.
Luckily, we report ABSTRACT_MEMBER_NOT_IMPLEMENTED additionally.
In K2, MODALITY_CHANGED_IN_NON_FINAL_EXPECT_CLASSIFIER_ACTUALIZATION
will be correctly reported as a compilation error

fixup! Fix `isKotlinFunctionWithBigArity` function
Fix `isKotlinFunctionWithBigArity` function
Previous implementation could return false positive results, e.g. for
class named `abacaba.kotlin.Function42`

The only case when erasure matters in a context of materialization of
`PromisedValue` is when the type is a type parameter which upper bound
is an inline class. Since `PromisedValue::materializeAt` is a hot spot
and `eraseTypeParameters` is an expensive operation, we should not do
type erasure in other cases.
Reporting it for `VIRTUAL_MEMBER_HIDDEN`
is ok, because `VIRTUAL_MEMBER_HIDDEN`
has always been an error, so we are
allowed to treat these as overrides
implicitly.

If some function is not fake-override, then its type should be just
default type of containing class
For fake overrides the default type calculated in the following way:
1. Find first overridden function, which is not fake override
2. Take its containing class
3. Find supertype of current containing class with type constructor of
class from step 2
^KT-60252 Fixed
This change uncovered the following problem in pipeline: we have a contract,
that all bodies will be generated after all fake overrides will be preprocessed.
But DataClassMembersGenerator generates bodies before f/o creation,
which leads to the problem, if data class has forward reference to some
class which was not processed before (because in this case generator
of `hashCode` function will try to reference f/o, which is not created yet,
which leads to `SymbolAlreadyBound` problem)
```
data class Some(val a: A) {
generated fun hashCode(): Int {
return a.hashCode() // (1) is not generated yet
}
}
class A {
fake-override fun hashCode(): Int // (1)
}
```
This problem will be fixed in the next commit
(related test is compiler/testData/codegen/box/ir/kt52677.kt)

It is true that for vararg parameter `arrayElementType` always have to
be not null, but it required resolution to TYPES phase. But in case of
the error type, the type reference is treated as resolved, so we are not
obligatory to resolve such reference to TYPES, because we already have
the resolved type.
So we can make the rule of KtFirValueParameterSymbol#returnType less
strict, and varargElementType will effectively do the same as
lazy resolve + arrayElementType
^KT-61422 Fixed
It was reported because in composite module analysis we have both expect
and actual annotation descriptors, which may differ.
This may lead to bugs in the checker of ACTUAL_ANNOTATIONS_NOT_MATCH_EXPECT
diagnostic.
`fqName` comparison can be safely removed, because we already check
types in `areCompatibleExpectActualTypes`.
Tests:
- typealiasedAnnotation.kt - for annotation use (so it has different
ClassId)
- typealiasedAnnotationAsArgument.kt - when typealiased annotation
used in another annotation as argument
- sourceRetentionAnnotationsWhenTypealias.kt - tests same as
compiler/testData/diagnostics/tests/multiplatform/annotationMatching/sourceRetentionAnnotationsWhenTypealias.kt
No special test added for opt-in, because it's prohibited to have
expect/actual opt-ins by EXPECT_ACTUAL_OPT_IN_ANNOTATION checker.

This behavior wasn't intended during KT-15470 coding. I only intended to
prohibit `@get:` target on things different from properties. But I
accidentally prohibited `@property` on things different from properties
too
But it's a bug fix anyway, so let's keep it.
I also re-checked the implementation of KT-15470, I don't see any other
unintentional prohibitions
