This diagnostic is reported in rare situations when
StubTypeForBuilderInference is kept as a parameter type
of for loop or lambda. Before this commit, we had in K1
"Could not load module <error module>" from IrLinker instead.

... 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.

Generally the wrapping anonymous initializer can be used as a
"containing declaration" for some elements, but since the initialiser
for the last script expression could be dropped (the expression could
be converted to the result property), this may lead to the surprises,
e.g. as described in KT-65984
This fix marks the last initialiser as local, preventing it from being
referenced as "containing declaration".

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`.
This code does lead to inferring
`Visibilities.Unknown`, but it's not
reported anywhere. This is because it
happens inside `AbstractIntSet` which
comes to us "pre-compiled" by javac,
whereas `FirOverrideChecker` only checks
members within `KotlinClass`.

The rule of thumb is the following:
If the `if` and `when` can be successfully replaced with `while`,
then it is used as a statement, otherwise, it is used as an expression.

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

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.

`testIntersectionOfPrimitiveBasedFunctions`
is fine, because we deprecate this
already in ^KT-63243.
`CANNOT_INFER_VISIBILITY` is
positioned as `DECLARATION_NAME`,
just in case we decide for
some reason that we do want to
report it along with
`MANY_*_NOT_IMPLEMENTED`. In that
case, we'd get a problem that
their bounds overlap, but not
completely contain one another.

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.

Constructors have their own list of hidden/visible.
We now require the constructor to be in VISIBLE_CONSTRUCTOR_SIGNATURES,
everything else is hidden.
This makes it unnecessary to check HIDDEN_CONSTRUCTOR_SIGNATURES

- 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

This only affects delegation operators as well as the for-loop-related
next and hasNext operators.
All the other operators worked correctly before.
In K2, the previously mentioned operator calls will be flagged with a
deprecation error and will become and error in 2.1.
