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.
Various HL API needs to create fake override for symbols in libraries.
Without module data it may fail. Following exception is an example:
java.lang.IllegalStateException: Module data is not registered in Libraries session

This is useful for quickfixes offering casts. We don't want to offer
user to cast incompatible types.
Also, explicitly allow compare to `Nothing` and handle `Nothing` from intersection
Also change
org.jetbrains.kotlin.fir.types.TypeUtilsKt#hideLocalTypeIfNeeded to skip
approximating anonymous objects if there are multiple super type refs so
that resolution behaves the same (for uncompilable code).
Note that this change does not implement check for
ApproximateAnonymousReturnTypesInPrivateInlineFunctions as the check is
already turned on in 1.5 and will likely not needed when FIR becomes
stable.
Previously the validation was inconsistent allowing non-incremental builds without Kotlin sources to pass successfully with JVM target misconfiguraiton but fail incremental builds
#KT-48408 Fixed
Previously we exported main function only.
Extend this feature to arbitrary number of annotated functions.
Type restrictions and conversions are similar to imported functions.
* Use fetch and instantiateStreaming
* Call main export if it is present
* Produce a variable with module name that contains a
promise of module exports
