In case of `inline fun <T : I<T>> foo(a: Any) = a as T` `T` is being
erased to `I<*>`

`mappedVarargElements` are populated with parameters from
`argumentMapping`, which is computed using `ArgumentsToParametersMapper`
which calls `original` on all value parameters (see
ArgumentsToParametersMapper.kt:136).
So the code that adds empty lists for unassigned vararg parameters
should also call `original`. Otherwise, in the added test, we ended up
with two arguments for the parameter `s` in `id(::base1)`, one for
`Base.s` containing the correct value, and another for `Derived.s`
containing the empty list. Psi2ir took the last one, which resulted in
empty array being passed to the vararg parameter.
Note that all of this is caused by the fact that `original` of a fake
override parameter is the parameter of the base function. This seems
suspicious because `original` of a fake override _function_ is that fake
override itself (NOT the base function), but this would probably be very
risky to change at this point.

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.

Since IDEA moved most of it's jars to java 11 it's illegal to use them
in our dependencies, so all modules which use `intellijDep()` should
carefully specify which jars they use
In case the cast value is used as a receiver to a private method call,
the cast is actually necessary, see KT-48927. Also, this optimization
has backfired once already (see kt48659_identityEqualsWithCastToAny.kt).
It seems that the best way to optimize these casts is not to generate
them in the first place, and/or use bytecode postprocessing.
Apparently the only kind of casts which need to be eliminated are those
which occur on an inline class to its supertype. Otherwise the
unsafe-coerce intrinsic is inserted at the incorrect place, and several
tests fail (uncastInlineClassToAnyAndBack.kt, genericOverride.kt,
classGenericOverride.kt).
#KT-48927 Fixed
These two fields references the parent of the import rather than the
classes that are imported. For example
```
import java.util.Map // resolvedClassId -> null
import java.util.Map.Entry // resolvedClassId -> java.util.Map
import java.util.Map.* // resolvedClassId -> java.util.Map
import java.util.Map.someStaticMethod // resolvedClassId -> java.util.Map
import kotlin.package.someTopLevelFuntion // resolvedClassId -> null
import kotlin.package.MyObject.someObjectFuntion // resolvedClassId -> kotlin.package.MyObject
```
ImplicitReceiverValue is mutable and FIR body resolve could alter it
while analysing code with smartcast. Hence, previously the IDE may see
inconsistent receiver values for a local scope. For example
```
open class A
interface Foo {
fun foo()
}
fun A.bar() {
if (this is Foo) {
// scope here has implicit receiver type to be `A` rather than `it<A, Foo>`
}
}
```
This change creates snapshots for local statements so later changes
during body resolve won't affect the collected context.
Assuming Java class `Super` has a protected `getName` method and a
public `setName` method.
Then, in a subclass of `Super`, FE1.0 allows calls to `setName` via the
property syntax if the property is protected and invisible due to
dispatch receiver is not `this` or `super`.
