... when the expected type is not a function type.
Instead set it to a new type variable.
This fixes a bunch of false negative CANNOT_INFER_PARAMETER_TYPE.

Before this commit, the expect-actual resolver could find expects in
regular dependencies
Note: The appeared `VIRTUAL_MEMBER_HIDDEN` in
compiler/fir/analysis-tests/testData/resolveWithStdlib/multiModule/FakeOverrides.kt
isn't caused by my change. It's caused by fixing the testData dependency
syntax notation.
The testData improperly used regular dependency syntax notation, while
it should have been using dependsOn
Before:
Regular dependency syntax notation
// MODULE: androidMain(commonMain)
After:
dependsOn dependency syntax notation
// MODULE: androidMain()()(commonMain)
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`.
In some cases we transform flexible type into non-flexible during
enhancement, but don't add `@EnhancedNullability` attribute to them,
which breaks consistency with K1 on IR level
This commit fixes it
^KT-65302
A class can inherit two declarations that are compatible from the
overridability standpoint and are therefore combined to a non-trivial
intersection.
At the same time, the class can declare a member declaration that
only overrides one of the intersection's members.
In this case, we break up the intersection and only add the overridden
parts to the declared member's direct overridden list.
If the class doesn't override the intersection, it exists as
intersection override, like before.
#KT-65487 Fixed
Even though SO may not be correct
overrides sometimes, it feels more
natural to treat fake overrides as...
well, "overrides". And without it
we'd need to make the code in
`FirOverrideChecker` less intuitive.
- Handle flexible types in recursion check
- Handle intersected supertypes separately
- Make check when not to approximate captured types in type argument
position more fine-grained.
Only apply it to case when the captured type is replaced by a star
projection.
All other cases are handled by recursive calls to
approximateCapturedType
#KT-65377 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.

We drop Kotlin function 'remove' or 'getOrDefault' from JvmMappedScope,
if it has platform-dependent annotation, and the bound Java class scope
does not contain a function with the same signature.

A report of UNRESOLVED_REFERENCE should not be made for elements like
FirImplicitThisReference that don't have a source, as they are implicit.
#KT-65044 Fixed
When there is a return statement within a lambda, and the return
statement contains a lambda, data-flow information from the inner lambda
is not being passed correctly to the surrounding lambda. This is because
return statements which had a lambda target would drop all postponed
lambda exits, but should instead forward those exits to the surrounding
lambda exit.
^KT-59729 Fixed

The primary constructor of a class needs to be the first subgraph of the
class control-flow graph. Based on the Kotlin specification, class
initialization order goes first primary constructor, in-place
declarations (properties and init blocks), and then secondary
constructors. If the class doesn't have a primary constructor, then it
is just skipped in the order.
Unfortunately, the class control-flow graph had in-place declarations
first and then all constructors. Instead, we should treat the primary
constructor as the first in-place declaration, and then continue with
the existing processing as secondary constructors. This will guarantee
that super constructor calls have the correct property initialization
information.
^KT-65093 Fixed
This fixes some type argument mismatch errors caused by a captured type
being approximated and then captured again.
Some places need to be adapted to work with captured types that
previously only worked with approximated types.
#KT-62959 Fixed
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.

- use `FirImplicitInvokeCall` instance check to detect implicit calls,
it is cleaner than checking particular resolve type and "invoke" name
- reuse `visitQualifiedAccesses` to update the CFG instead of manually
searching through the `localProperties` (because it didn't work in the
case of overloads)
^KT-64832 Fixed
^KT-61032 Fixed
There might be several pathes out from the function from CFG point of view:
- normal execution path
- exceptional execution path
For verification of callsInPlace contract it's needed to check only
the normal path

This is required for the following commit where candidates from the
original scope in presence of smart cast will not be ignored if they're
the same symbol.
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.

Previously, there was a contract that each callable symbol in the chain
of `processDirectOverriddenWithBaseScope` will be unique. And if some
symbol is accessible from multiple scopes, then only last of them will
be returned as a component of `MemberWithScope`. So there actually was
no such thing as "pair of two different MemberWithScope with the same
symbol and different scopes"
After the change of `processDirectOverriddenWithBaseScope` contract (see
previous commits) each scope returns `MemberWithScope` for some symbol
with the previous scope in the hierarchy even if it contains the same
symbol as the current scope
So now scope is actually a part of `MemberWithScope`, which should be
considered as part of equality. Otherwise, we can skip some part of
the overridden hierarchy, because we will start to consider symbol as
visited after its first occurrence (in opposite to the previous behavior,
when only the last scope was returned)
Previously, there was a contract that each callable symbol in the chain
of `processDirectOverriddenWithBaseScope` will be unique. And if some
symbol is accessible from multiple scopes, then only last of them will
be returned as a component of `MemberWithScope`
But after the change from previous commit, we don't have this contract anymore.
Which means that we may meet the same symbol during processing hierarchy
of overridden functions (but with different base scopes)
So if some code utilizes `process...Overridden...WithBaseScope` functions
it should consider that the same symbol may be obtained several times

Pass constraint errors from the integration system into a candidate to
make sure it is reported later.
