Before this commit we considered !isOverride as a sign that
function / field / accessor has no overridden symbols.
However, it's false for deserialized, because isOverride
is always false there.
This commit fixes 68 BB tests but breaks 25 BB tests (not yet muted)
Attributes are used to name continuation classes and are generated
before inline classes processing. During the processing, for override
functions in inlined classes, the compiler generates
STATIC_INLINE_CLASS_REPLACEMENT function with body of the override.
The override's body is replaced with delegating call to
STATIC_INLINE_CLASS_REPLACEMENT. However, since we need to keep the name
of the continuation class, we copy attributes from the override to
STATIC_INLINE_CLASS_REPLACEMENT. This leads to attribute clash during
AddContinuationLowering.
So, to fix the issue, do not use the attribute of
STATIC_INLINE_CLASS_REPLACEMENT in original->suspend map.
As an optimization, do not generate continuation for the override
function.
For single super type constructor create star projection argument when types for that argument are equal to the original types.
Captured star projections are replaced with their corresponding supertypes during this check.
Skip check for `in` parameters, for which recursive cst calculation does not happen.
Adjust constant in fallback recursion condition.

Since LocalDeclarationsLowering is a BodyLoweringPass, local
functions inside one declaration are handled independently of local
functions in the other declaration. This can lead to name clashes, in
case a local function with the same name and signature is declared in
overloads in the same container, which results in a signature clash
error in JVM IR.
The issue became more common with the introduction of adapted function
references, where psi2ir generates a local adapter-function with a
predefined name, which can easily clash with another reference to the
same target in an overload. This led to a compilation error when
bootstrapping Kotlin with JVM IR, for example in GradleIRBuilder.kt
where there are a lot of references to the same function.
