- `invoke` method must always start a suspend functions
- For creation of coroutine that has not been started yet, there are
two special internal interfaces `SuspendFunction0`/`SuspendFunction1`
The meaning of `setDropOriginalInContainingParts()` call is that
it makes copyBuilder forget the original parts, in particular
the valueParameter.original.containingDeclaration does not reference
original descriptor no more
Otherwise the following exception is happening:

- move getDelegates from CodegenUtil to DelegationResolver, reuse it in
DelegationChecker
- use getAllOverriddenDescriptors + filterOutOverridden instead of a manual DFS
Gradle can wipe system properties between the build.
If this property is not set, "idea.properties is not found exception"
can be thrown when creating KotlinCoreEnvironment.
Reasons for moving:
1. Integration with Kotlin daemon for Gradle.
Gradle bundles Kotlin compiler (kotlin-compiler-embeddable) since Gradle 3.2.
There is no plugin isolation in Gradle, so strange compilation errors/exceptions may happen.
We decided to fix this problem by compiling out-of-process using Kotlin daemon.
Reasons for moving IC to the compiler:
* Better isolation from Gradle process.
* Incremental compilation logic is not scattered across two process and multiple modules.
* Makes it possible to implement standalone CLI IC
We made it because of non-stable name resolution when project is multi platform. For such projects in platform module we have two classifiers with the same name, but impl class or type alias should win!
