The only case when behavior is change is described at
computeNonTrivialTypeArgumentForScopeSubstitutor
The idea is to avoid depending on the presence of @UnsafeVariance
and instead approximate captured types in covariant argument positions
before building substitution scopes
It's correct because for Captured(*) <: Supertype,
Out<Captured(*)> <: Out<Supertype> and when we've got @UnsafeVariance
value parameters at Out, it's ok to allow passing Supertype there.

Otherwise, when we come to `ClassCodegen.kt:173
for `GradleActionTest` and check
`FUN FAKE_OVERRIDE name:<get-project>`,
we then go to `JvmSignatureClashDetector.kt:37`,
and call `mapRawSignature(overriddenFunction)`
which ignores the original `@JvmName`.
It does so because it relies on the property copy
which forgets to copy the getter, but
`@get:JvmName` is stored in it.
Extra when-branches for `FAKE_OVERRIDE` are needed,
because otherwise the annotations would not
be copied in `Fir2IrDeclarationStorage.kt:723`.
Extra when-branches for `DELEGATED_MEMBER` are
needed, because otherwise the generated IR changes
in some tests. For example, see:
`FirLightTreeIrTextTestGenerated.Declarations.testKt35550`.
The `assumesBackingField`-related change is backed by
the `FirLightTreeIrTextTestGenerated.Stubs.testJavaEnum` test.
`this.body = null` ensures the resulting IR
matches K1.
The change in `FirImplicitBodyResolve.kt` is needed,
because otherwise the bootstrap compiler fails at
`:compiler:frontend:compileKotlin`,
but I didn't come up with a smaller test for it.
If we don't make an explicit accessor copy,
then when we later create a `Fir2IrLazyPropertyAccessor`
for the fake override getter, it's `fir` will
be a reference to the `FirProperty`, not `FirPropertyAccessor`.
That's why `DumpIrTreeVisitor` will render `IntrinsicConstEvaluation` as
a getter annotation as well.
`FirPsiIrTextTestGenerated.testDelegatedGenericImplementation`
renders type parameters from `<get-x>`,
because when assigning `extensionReceiverParameter`
of the setter `<set-x>` we come to
`Fir2IrClassifierStorage.kt:638`,
and in this cache there's the parameter with
the `<get-x>` parent.
Note that `typeContext.origin == DEFAULT` in
`getCachedIrTypeParameter`.
It's `DEFAULT` because at the line `Fir2IrDeclarationStorage.kt:335`
the `function` variable is `null` (because there's no setter).
The change in `declarationAttributes.kt` is backed
by the `FirPsiIrTextTestGenerated.testKt45853` test.

Merge-request: KT-MR-9210

We've muted some irText tests on JS in the previous commits because
test expectations in some tests are different when targeting JS.
AbstractKlibJsTextTestCase tests use a different logic:
they compare the dump of the deserialized IR with the frontend-generated
IR, not with the expectations in text files, thus muted tests weren't
actually failing.
Here we introduce a temporary fix, namely
a separate // IGNORE directive for klib tests.
When klib tests are moved to the new test infrastructure, there will be
no need to do this.
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
This change allows to revert adding `WITH_STDLIB` directive
to tests which happened at `a9343aeb`.

The expression needs to be resolved first to determine if there is a
receiver that needs to be extracted to a temporary variable. Also, the
special case for prefix increment/decrement on local variable without
delegates requires resolution to check if the variable is local.

See the relevant test at t/
estData/codegen/box/sam/contravariantIntersectionType.kt
After the previous commit, when generating a call for `doOnSuccess {}`,
we have a SAM type with removed projection Consumer<Any?>, while
real function type of the lambda is a bit different
(Function1<ConcreteType & ConcreteType2>).
While for me, that looks questionable, but in K1 it was effectively
resolved via the same implicit cast that on JVM is generated to an
INVOKEDYNAMIC that wraps initial function-typed value.
^KT-53552 Fixed
It would be more consistently to prohibit the behavior from the unmuted
test (see KT-52428), but it was decided to postpone the breaking change.
Unfortunately, it didn't work to make a test where for computing
star projections we would need to substitute other type parameters
because effectively, it's not allowed to have SAM conversion when
star projections/wildcard is based on a type parameter which bounds
use other type parameters.
^KT-53552 In progress
Namely, do not choose `Nothing?` result type when fixing a variable
that has other constraints besides the ones that came from
the relevant type parameter's upper bounds.
See more details in KT-55691.
In K1, the case from specialCallWithMaterializeAndExpectedType.kt
was working (inferred to String?) just because the branches
were analyzed independently with `String?` expected type.
This change became necessary after the previous commit when we united
inference subsystems for if/when branches (see motivation there).
NB: For K1, the behavior is left the same, but the code
was refactored a bit.

Beside some corner cases, it's already prohibited in K1 because
adaptation have a bit strange nature
(they don't represent any existing real function exactly)

This fixes "IllegalStateException: Fir2IrSimpleFunctionSymbol for

^KT-56072 Fixed
- The fix for KT-55570 caused some backend tests to fail, because errors
are now correctly reported for simple classes and actual/expect in
the same module is not supported in FIR. See KT-55177.
- The commit also adds separate tests for K2. Unfortunately, these have
to be disabled for K1 because K1 then reports "expect without actual"
errors.
In details, this commit changes the following:
- it converts FIR when without branches to empty IR block without when
- it doesn't drop empty else branches in when anymore
* `return` should only be added to the last statement if the return
type is not Unit
* If there is a `return` without an argument, then the expected return
type is Unit and the last expression is not a return argument (unless
it's an incomplete call, in which case it is inferred to return Unit;
this behavior is questionable, but inherited from K1)
* There should be a constraint on return arguments even if the expected
type is Unit, otherwise errors will be missed
* When the expected type is known, using the call completion results
writer is pointless (and probably subtly wrong).
