It's not that simple because we still need inline functions bodies
and classes fields which aren't present in Lazy IR. To overcome this,
save additional binary info for a cached library and then use it when needed
Parameter of a synthetic SAM adapter always has a function type (not a
subtype). Checking for the subtypes broke the case from KT-46908, where
fun interface is itself a subtype of a function type.
#KT-46908 Fixed
Consider the following code:
```
fun test(a: List<String>) {
a.first()
}
```
The dispatch receiver type of `first` in this case is `List<T>` before
this change. After this change, it's `List<String>`.
In addition, this change also replace the dispatch receiver type with
the more specific type if available. For example, consider the following
```
class MyList: ArrayList<String>()
fun test(a: MyList) {
a.get(0)
}
```
The dispatch receiver type of `get` is `MyList`, instead of
`ArrayList<String>`. That is, a fake override is created in this case.
Also, don't bother ensuring that the upper bound has the same tree size
as the lower bound; the new index computation can handle it when some
subtrees of the lower bound are replaced by star projections in the
upper bound.
1. this should've been only done if the language feature for validating
that is disabled;
2. that feature probably won't matter by the time FIR is stable;
3. it only worked because type enhancement of type arguments is broken
anyway - a more correct hack would be to provide a custom
ConeTypePreparator.
Descriptors are already supposed to be sorted in scopes. The problem is
that rendering descriptors for sorting takes a lot of time (~1.5% of
total compilation time of intellij with JVM IR), and simple heuristics,
like comparing by names first, don't fully help with it.

These tests are not passing because of the way how test system works.
To works properly interpreter needs source files. For now they are
passed as additional source files, but this method is not working
for old frontend, some conflicts appear in symbol table. Best way to
fix it is to wait until ir serialization.
Now supported default args:
1. from super class or interface;
2. with field access, declared in interface;
3. with field access, declared in outer class.
