There are still some places in `.fir.kt` where false-positive reports
remained. This is because of IR checker, which will be fixed in next
commit.
^KT-31636
After previous commits IrActualizer runs only there are at least two modules
in backend input. So to check diagnostics from Actualizer all tests
should contain at least two modules
Diagnostics in test `extendExpectedClassWithAbstractMember.kt` were
changed because there is an exception from IrActualizer caused by
errors from frontend (`ABSTRACT_METHOD_NOT_IMPLEMENTED`), which is
swallowed by this kind of tests
Fir2Ir conversion consists of multiple steps with complex logic (like
conversion of each module, actualization, plugins application, constant
evaluation), and to ensure that they all are executed correctly it's
convenient to have the single entry point for all this machinery
`fir2IrComponents`, `irActualizerResult` and `dependentIrModuleFragments`
were used in `IrActualizerAndPluginsFacade`, which was removed in the
previous commit
IR actualization and IR plugins will be moved into base Fir2Ir facades
in the following commits, so this facade is not needed anymore
It was easier and cleanlier to remove this facade first and only after
that modify base facades
FirDefaultArgumentsInExpectActualizedByFakeOverrideChecker is an adhoc
checker which can be converted to ExpectActualCheckingCompatibility to
reuse common expect-actual checking infrastructure.

Review: https://jetbrains.team/p/kt/reviews/13094/timeline
Tests that were broken by one of my previous commits are now fixed:
- actualFakeOverride_paramsAreCompatibleViaSharedMethodWithDefaultParams.kt
- inheritedJavaMembers.kt
DEFAULT_ARGUMENTS_IN_EXPECT_ACTUALIZED_BY_FAKE_OVERRIDE diagnostic
disappeared in delegation.fir.kt because only one
AbstractExpectActualChecker incompatibility can be reported at a time
(DEFAULT_ARGUMENTS_IN_EXPECT_ACTUALIZED_BY_FAKE_OVERRIDE is now reported
not by adhoc checker but by common AbstractExpectActualChecker). It
would be nice to report both of them, but it's a separate issue KT-62631
delegation2 test makes sure that
DEFAULT_ARGUMENTS_IN_EXPECT_ACTUALIZED_BY_FAKE_OVERRIDE is reported when
NO_ACTUAL_CLASS_MEMBER_FOR_EXPECTED_CLASS is fixed
^KT-63550 Fixed
Review: https://jetbrains.team/p/kt/reviews/13094/timeline
Now it's required to create a new ScopeSession when searching for expect
members for actuals. If you keep reusing actualScopeSession then members
declared in platform may "slip into" the search results, resulting an
incorrect expect for actual (e.g. it happens in
supertypeIsExpectActual_covariantOverrideOfInjectedFromSuper_transitiveSubstitutionFakeOverride.fir.kt)
I suppose that it always has been a bug that we reused
actualScopeSession because we were mixing actualScopeSession and
expect FirSession (which is a bad idea), but we simply didn't have cases
where this bug could be observed. Now after we started matching
fake-overrides, we have such cases.
But creating a new ScopeSession every time is a suboptimal solution. We
need to design a scope caching KT-63773
This call to isAbstractMethodOfAny was in Fir2IrLazyClass since its
inception in 0622be14a5, and there's no explanation why this was
necessary. Removing it does not seem to break anything, but fixes the
case when IrFakeOverrideRebuilder is enabled and when Java base class
declares an abstract equals/hashCode/toString which is not overridden in
the Kotlin subclass.

When flattening a dependency FirSymbolProvider, make sure transitive
dependency FirSymbolProviders are not included. This requires checking
that nested symbol provider sessions match the composite symbol provider
session when they are both source sessions.

To make it possible to change nullability of IrCapturedType and change
its annotations, which is happening when determining overridability of
functions via IR.
#KT-63437 Fixed
Some boolean expressions could be transformed into `IrWhen`
node. To understand that this node is actually
a boolean expression, we need to analyze its origin.
#KT-62683
In certain situations like constructor calls, it's possible
to have different WasExperimental/SinceKotlin pairs associated
with one use-site, e.g. a constructor call is associated both
with a constructor declaration and a class declaration.
However, looks like it make no sense to handle this situation
in FirSinceKotlinHelpers, because FirOptInUsageBaseChecker already
handles them.
