For special calls (when-expressions, if-expressions, etc.), do not attempt to
get type of the argument expression, which is the block with the callable
reference, instead get type of the callable reference itself. The difference
matters because for block expressions, a new lexical scope is created for each
getTypeInfo (see ExpressionTypingServices.getBlockReturnedType), and we do not
support rewrites of this value in the binding trace
#KT-12044 Fixed
- `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:
