If the session is from the other module, it might not know about
FirFiles which are relevant for transforming and resolving the
declaration
^KT-52136 Fixed
In qualified expression like `foo().`, selector expression is null.
Because of that the whole expression was marked as an error FIR
expression, and `foo()` part was not resolved at all (including
arguments and everything else).
This commit fixes the problem by providing receiver's FIR expression
as an underlying expression for error FIR expression. That way
it will be seen by all resolve transformers and will be successfully
resolved.

Previously (few commits earlier), it contained two versions
of receiver (lhs) generated separately for each desugaring version
that looked a bit redundant.
Now, at FIR building stage we just don't create desugaring sub-trees,
instead they are being built during bodies transformation and that seems
to be much convenient there, since we don't need to reverse-engineer
get-set-operator version to check if containing calls are successful
(as we just built those calls and retain them)
Semantically, this changes may only change how data flow works
for such statements (see changed compatibilityResolveWithVarargAndOperatorCall.kt)
^KT-50861 Relates
This big refactoring is needed to cleanup building of overrides
mappings and prevent creating redundant intersection overrides in
cases when there is no need in them:
```kotlin
interface A {
fun foo()
}
interface B {
fun foo()
}
interface C : A, B {
override fun foo()
}
```
Before this refactoring there was next override tree:
C.foo
intersection override (A.foo, B.foo)
A.foo
B.foo
Also this commit fixes special mapping of overrides in jvm scopes
for declarations which have kotlin builtins in supertypes with
special java mapping rules (collections, for example)
When stdlib is represented as a source dependency (which seems to be the
case in the `kotlin` project), it will be resolved lazily for the IDE.
Same thing can happen if someone decides to "extend" the stdlib
by declaring their declaration in the `kotlin` package
In both of those cases, we need to make sure that receiver type is fully
resolved before trying to get a `coneType` from it
N.B. To make resolve tests work, I've added a separate folder
`withAllowedKotlinPackage` to the `testData`, because in the default
test setup it is not allowed to extend the `kotlin` package by user's
definitions
^KT-50728 Fixed
When lazy resolve is involved, type bounds can be in an unresolved
state (e.g. `FirUserTypeRef` instead of `FirResolvedTypeRef`). To
enforce the resolve, we use `resolvedTypeBounds` where it might be
important
^KTIJ-20618 Fixed
There just should be a different facades for cases
A<T1, T2> and foo<T1, T2>()
Test data has changed for type alias constructors since previously,
it was working by mistake because of assumption that type alias arguments
are linearly mapped to the type parameters of the corresponding constructors
^KT-50703 Open
If some java class has multiple supertypes then we need to collect
overriddens from all those types directly, even if superTypeScope
(which is FirTypeIntersectionScope in this case) returns only
one symbol from one of this types (not intersection one)
This is needed to proper enhancement in cases when some type occurs
multiple times in supertypes graph with different nullability
of arguments:
class ConcurrentHashMap<K, V> : AbstractMap<K!, V!>, MutableMap<K, V>
If we try to find method `get(key: K): V` supertype scope returns
`AbstractMap.get(key: K!): V!` (because it actually overrides
`MutableMap(key: K): V?`), but we need to get both symbols to
properly enhance types for `ConcurrentHashMap.remove`
We are going to deprecate `WITH_RUNTIME` directive. The main reason
behind this change is that `WITH_STDLIB` directive better describes
its meaning, specifically it will add kotlin stdlib to test's classpath.
