Only top-level types on fields, methods' return types and
value parameters are supported to catch-up how class-files are loaded
in IntelliJ (see IDEA-153093)
NB: this commit also affects

- Apply default qualifiers to type arguments if they contain TYPE_USE
in applicability list
- Read TYPE_USE placed default qualifier annotations

The regression appeared after
b5a8ffaddc
when we started trying both static and member methods until
first success and when there is no successful
we were just leaving the last one (e.g. private member)
But the actual problem is that we were commiting the trace
in case of single (but incorrect) result in resolution mode of
SHAPE_FUNCTION_ARGUMENTS when we couldn't yet choose the
correct static method
Also we shouldn't choose a shape for callable reference
using only the knowledge that result is single:
it may lead to the wrong inference result
(see test with Pattern::compile)

The problem was that in `Function<T>.apply(T)` T is now not-platform,
so when checking if not-null assertion is needed for parameter in SAM,
it's defined by the upper bounds of T that is a platform (Any..Any?),
and while it's definitely not marked as nullable it's still nullable
in a sense that it can contain null as a value.
So the solution is obvious
#KT-16413 Fixed
A lot of problem arise with current solution
(loading them with lowpriority annotation + additional call checkers):
- We errorneously treated ArrayList.stream as an existing method, while
it's just a fake override from List
- The same problem arises when creating a class delegating to List.
Also the latter case is failing with codegen internal error
(see issue KT-16171)
The negative side of this solution is that instead of reporting meaningful
diagnostic, there will be UNRESOLVED_REFERENCE.
But it seems to be better than having strange problems like ones described above.

See doNotCaptureSupertype test for clarification:
When resolving b.collect(toList()) we're building a common system with
two variables T and R.
The problem was that when introducing the constraint
C<T, Inv<T>> <: C<in String, R> we then were seeing the constraint
T <= in String, and add the constaint T=Captured(in String)
That lead to R=Inv<T>=Inv<Captured(in String)>, and after approximation
R=Inv<in String>, that is not the desirable result (Inv<String> suits here)
But the root problem was that we add captured constaint when projection was from supertype,
that seems to be wrong, and for example Java doesn't do that in the similar situation.
#KT-11259 Fixed
Inferred type of receiver of orElse is Optional<T & Any>
Generic descriptor is orElse(E!): E!
Substituted descriptor is orElse(T): T , and that is the problem.
Seems that E! => (T & Any)! gets expanded to just T or T & Any , however it should be expanded to
(T & Any) .. (T & Any)? => T & Any .. T & Any
T & Any is NotNullTypeParameter(T)
The problem is that (T & Any)? is expanded to T & Any,
that is seems to be wrong.
#KT-15236 Fixed
- In tests on built-ins with no sources, just call
JvmResolve.analyze(environment) and inspect the resulting module
- In AbstractLocalClassProtoTest, create container via
TDAForJVM.createContainer
- Inline single module container creation into AbstractDiagnosticsTest
