The current implementation doesn't consider Foo a subtype of Captured<in
Foo>!!, since AbstractTypeCheckerContext::checkSubtypeForSpecialCases
does not handle DefinitelyNotNullType cases. This PR adds handling of
DefinitelyNotNullType by looking at its original type.
^KT-42824 Fixed
The issue is the type checker doesn't consider P? a subtype of
CapturedType<in P>?, whereas P a subtype of CapturedType<in P>?. In
AbstractTypeCheckerContext::checkSubtypeForSpecialCases, it checks if
P? is a subtype of the lower type of the captured type, which is
P, and returns false.
This fix uses nullable version of the lower type when the captured
type is marked nullable. To check if P? is a subtype of Captured<in
P>?, we check the LHS, P?, against the nullable lower type of RHS,
P?.

Put their content to constructor-impl, so they are called during
constructor call, but they are not called during boxing, because
box-impl calls <init> and not constructor-impl.
#KT-28055 In progress
The main change here is in `JvmInlineClassLowering.visitFunctionAccess`,
where we now store the substituted return type of the function as the
type of the call expression. Without it, the call could have a
meaningless type, e.g. some `T` which is inaccessible at that place, and
that could backfire in subsequent lowerings in codegen. For example, in
the `stringPlus.kt` test, it would prevent the code in
`FlattenStringConcatenationLowering.isStringPlusCall` from recognizing
and replacing the `String.plus` call, leading to a codegen exception.
Other changes are mostly cosmetics to make the code similar to
`visitFunctionReference`, and preventive optimizations for the case when
the substitution map is empty.
The inline class is boxed when we pass it as lambda argument, now we
unbox it. If the underlying type is not Any or Any?, bridge method does
the unboxing.

instead of statically registering it.
Static registering can cause subtle errors when plugin implementation
(e.g. SerializationDescriptorPluginForKotlinxSerialization) is registered
from multiple classloaders: in multi-module with daemon compilation scenario
#KT-41857 Fixed
All inline classes should be boxed coming in and out of lambdas,
however, if the inline class was returned non-locally, it was not boxed.
This change fixes the issue in Old JVM BE.

Make sure that `message` and `cause` are properly configured
- synchronize IR BE and Legacy behaviour
- fix corresponding IR lowering
- fix JS IR core runtime
- add test
- fix KT-39964
Otherwise behavior might change because enhancement may force computation
for other type parameters in cases like:
class A<X extends Y, Y extends X> {}
See the test:
org.jetbrains.kotlin.checkers.DiagnosticsTestGenerated.Tests.J_k#testRecursiveRawUpperBound3
`in x` is represented as `<subject expression> in x` in psi, so
generating the entire call and then replacing the argument with a read
of a temporary results in redundant regenerations of the subject.
