Putting them in the local variable table means that the debugger
needs to have special handling for parameters with specific names.
That forces us to generate mangled names for these.
Instead of also implementing the name mangling for FIR, this
change gets rid of the parameters from the LVT instead.
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.
