Optimization in 2439c22ff6 introduced an array `absentArguments` with
default values of all parameter types, which is copied in `callBy`
instead of being recomputed each time. Unfortunately, its size was
computed incorrectly: `maskSize` should only take into account
value parameters (see the `parameter.kind == KParameter.Kind.VALUE`
check in `callBy`).
This led to an issue where if the function had 32 * N value parameters
and 1 receiver parameter, `maskSize` was greater by 1 than expected,
which caused an exception due to mismatching argument array sizes.

Tests:
- MultiPlatformIntegrationTestGenerated
- CliTestGenerated
- MultiPlatformIntegrationTestGenerated
- DiagnosticTestGenerated.Multiplatform
- FirLightTreeOldFrontendDiagnosticsTestGenerated
Also add -Xexpect-actual-classes flag to all necessary ./libraries/* modules
Otherwise compilation of those modules failes because of `-Werror`
It would be nice to report more appropriate diagnostics at the
corresponding places, but right now it's more important to
fix greenness-redness problems. Plus, this is already how K1 works.

Now that files have a CFG, use it to validate properties are initialized
correctly. Update FirTopLevelPropertiesChecker to collect initialization
info for the property being checked - similar to
FirMemberPropertiesChecker - and validate proper initialization.
#KT-56683 Fixed
#KT-58531 Fixed
In order to properly analyze top-level property initialization, a
control-flow graph must be created for FirFiles. This change adds the
foundation for the file CFG and updates body resolve to create the CFG.
Checking the CFG for proper initialization is separated into a following
change to ease code review.

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

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)
