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
Prepend the platform name to the diagnostic in a common module, which is
reported when sources of that common module are analyzed as a part of the
platform source set: "<!JVM:...!> ... <!>". Fix some existing tests, mostly by
adding "impl" to implementations
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
Not all the `hasNext` operators return types is exactly Z,
suspend operators return boxed versions.
So the fix is just coercing result value after invoked function to Z
This change should make the logic a bit more simple.
For all suspend functions/coroutines treat them in expression codegen
like they return boxed version of the original type.
Everything works fine then, except Unit type functions:
their bodies must be generated just like they're VOID and then load
Unit on stack manually.
Inline functions with reified type parameters are generated as private (see
AsmUtil.specialCaseVisibility), so we should treat them as "declared" in
reflection to look them up via getDeclaredMethod, not getMethod
#KT-14721 Fixed
'SuspendFunction$n' class descriptors are created on demand by KotlinBuiltIns (and cached).
On serialization, types constructed with 'SuspendFunction$n' are written as 'Function$n' with extra flag (SUSPEND_TYPE).
On deserialization, corresponding 'SuspendFunction$n' classes are used.
