This change allows to revert adding `WITH_STDLIB` directive
to tests which happened at `a9343aeb`.

This inconsistency is present due to not using the `// WITH_STDLIB`
in the above tests. When K1 creates the enum, it tries to generate
`entries()`, and for that it tries to load `kotlin.enums.EnumEntries`,
but this is actually an unresolved reference. K1 silently swallows it,
and proceeds.
The reason K2 doesn't fail is that in order to generate `entries()` it
simply creates the necessary `ConeClassLikeType` with the desired
`classId` instead of loading the whole `ClassDescriptor`.
The reason we can still observe `$ENTRIES` and `$entries` in K1
is because they are generated during the JVM codegen, and it
only checks if the `EnumEntries` language feature is supported. It
doesn't check if the `entries` property has really existed in IR
(by this time it's expected to have already been lowered to the
`get-entries` function - that's why "has ... existed").
The reason why the codegen doesn't fail when working with
`kotlin.enums.EnumEntries` is because it creates its
own `IrClassSymbol`.

- Materialize unit when its value is actually needed.
- Special-case Unit_getInstance return type at codegen. It should be a
proper Unit object instead of a "void"
This commit handles "subclass: super-interface by delegate-expression".
During Psi2Fir, for each delegate, we add to the subclass a synthetic
field (which has type super-interface), and an assignment of the
delegate-expression to the synthetic field in the primary constructor,
so that the delegate-expression can be resolved and transformed along
the way.
During Fir2Ir, we look up delegatable members from the super-interface
and generate corresponding functions/properties for the subclass.
TODO: support for generic delegatable members and generic
super-interface.
Currently FirThisReceiverExpression of instance methods are translated
to references of the class' thisReceiver,
not the method's dispatch receiver,
which causes problems with IrFrameMap::typeOf,
as the class' thisReceiver is not in the typeMap.
This commit translates non-qualified "this" references of
instance methods to references of the methods' dispatch receiver.
Quoted from https://kotlinlang.org/docs/reference/classes.html
"On the JVM, if all of the parameters of the primary constructor have
default values, the compiler will generate an additional parameterless
constructor which will use the default values. This makes it easier to
use Kotlin with libraries such as Jackson or JPA that create class
instances through parameterless constructors."
Inner class constructors should use the argument instead of reading
outer `this` from a field because if such an access happens before a
delegating constructor call, e.g. when evaluating an argument, a JVM
bytecode validation error will be thrown. (The only operation on `this`
allowed before a delegating constructor call is SETFIELD, and only if
the field in question is declared in the same class.)
This change reverts the AssignmentTranslator logic to a previous state
of "if we assign to a val, tranlate to backing field". Previously a
check whether or not we are inside of a constructor was added. The
check didn't detect secondary constructors, hence initializing of
val's with backing field started to work incorrectly.
The check itself was added in an attempt to prevent augmented assignment
operators to reference the backing field. The check seems to have been
wrong, because an augmented assignment could happen inside a construcotr.
A more correct fix was added later. It seems that it is safe now to
revert the logic back and rely on the frontend to only allow assignment
to a val property during initilization.
