This fixes a false negative NO_ELSE_IN_WHEN in K2 and incidentally
also fixes a false positive NO_ELSE_IN_WHEN in K1 since the fix is in
the common code.
#KT-62491 Fixed
Currently, PROPERTY_WITH_NO_TYPE_NO_INITIALIZER is reported for local
variables, but not reported for member or top-level properties. Add a
check to the common `checkPropertyInitializer` for when a property
type cannot be determined from the getter.
This also corrects a K1 versus K2 inconsistency, where K2 would allow
blocks from getters to determine property type instead of only allowing
expression bodies.

There was a case when we visited the same declaration multiple times
because of forward-referencing and visiting with designation
So because of this there were two changes required:
- remove assertion about visiting the same declaration twice (it's fine
since we don't actually resolve annotations twice)
- not skipping resolution of class children if annotations on this class
are already resolved

K1 reports `ARGUMENT_TYPE_MISMATCH`
and `TOO_MANY_ARGUMENTS` together, and
one way to do it in K2 is to say that
their kinds of inapplicability difference
is not relevant to the user.
Note that K1 doesn't do such filtering,
so this change "makes K2 closer to K1",
but still different.

fixup! [FIR] Show ARGUMENTS_MAPPING_ERROR diagnostics along with INAPPLICABLE
It's effectively a breaking change (^KT-62558)
K2 assigns flexible type to all static fields (from Java) and, for example,
`String? becomes String unlike K1. It affects IR signature generating.
That's why signature dump is disabled for some tests.

^KT-61786 Fixed
See the `privateInFile.fir.kt` test.
Type mismatches are simply confusing.
`inheritorOfExpectSealedClass.out`
reports unresolved reference probably
because now it resolves into the expect
declaration, rather than the actual one.
K1 doesn't report UNRESOLVED_REFERENCE
in this case. But this is red code
anyway. And this behavior still
depends on the order in which the compiler
receives both the declarations.

This is needed because in order to figure out which declarations are
visible from anonymous objects in terms of overridability (see
`FirVisibilityChecker.isVisibleForOverriding`), we need to get the
package name of that anonymous object, because there's package-private
visibility on JVM.
#KT-62017 Fixed
See the comment at updateSubstitutedMemberIfReceiverContainsTypeVariable
It became necessary after delegate inference is rewritten, since before
that happened, stub types were being left there and FIR2IR handled
them accidentally properly because stub types are equal to anything.
But that wasn't really correct even there because stub types are not
intended to leak out of the FIR

IllegalArgumentException: class
org.jetbrains.kotlin.psi.KtLambdaArgument is not a subtype of class
org.jetbrains.kotlin.psi.KtExpression for factory
TYPECHECKER_HAS_RUN_INTO_RECURSIVE_PROBLEM
was reported when TYPECHECKER_HAS_RUN_INTO_RECURSIVE_PROBLEM was
reported on a FirLambdaArgumentExpression, report it on its
`expression` instead.
#KT-60380 Fixed
UncaughtExceptionPath edges are used to influence smart-casting within
catch and finally blocks. Previously these edges were added from every
node which could throw an exception. But only assignment nodes influence
smart-casts by resetting inference back to some less specific type.
Therefore, instead of tracking every possible node which could throw an
exception - even though almost every statement node can - only add edges
from assignment nodes to catch and finally blocks. This fixes many
missing exception cases and also reduces the total number of incoming
edges to catch and finally blocks.
#KT-56872 Fixed
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.
^KT-59900 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.
KT-56683
When checking for class val property reassignment diagnostic, property
initializers should be treated as part of the class initialization.
However, property accessors should not. Previously, only the property
itself was checked for both of these situations and resulted in not
reporting diagnostic within property accessors.
#KT-59744 Fixed
This prevents `FirConflictsExpressionChecker.kt`
from missing conflicting local functions. It used
to due to inconsistencies in assigning `<local>`,
and this commit makes it a bit more
straightforward.
The change in KtClassTypeQualifierRenderer
prevents `FirOverrideImplementTest.testLocalClass`
from failing in `intellij`. It didn't fail for
callables, because `KtCallableSignatureRenderer`
doesn't try to render packages.
^KT-59186 Fixed
The change in `FirPsiDiagnosticTestGenerated.Resolve#testCast`
only highlights the existing
problem that we don't assign a
valid type to `_`.
^KT-58906 Fixed
This change prevents going up the scopes once we find a
substitution override. Whatever we'd find by going further is not
going to be a direct overridden anymore, so it would lead to incorrect
results when collecting direct overridden-s. Without this change, we get
error modules in FT intellij.
In positions outside of calls (e.g. property initializers)
we resolve callable references using a synthetic outer call with the
expected type as parameter type.
If this fails, we previously returned an unresolved reference.
After this commit, we additionally try to resolve the callable reference
with expected type Any.
This lets us report more precise diagnostics like type mismatches or
when multiple overloads exist NONE_APPLICABLE.

This is needed to be able to precisely distinguish different synthetic
declarations (like fields for delegates and functions for data classes)
