Introduce COMMON_COROUTINES_TEST directive.
Every test with this directive is run twice: one time with
language version 1.2 and kotlin.coroutines.experimental package
and the other time with language version 1.3 and kotlin.coroutines
package. Each run is a separate method: with suffixes _1_2 and _1_3
respectively.
However, since codegen of release coroutines is not supported in JS
backend, we generate only one method: with suffix _1_2.

Condition was too strict
if @JvmDefault implicitly hidden by class in inheritance.
Diagnostic is redundant cause there isn't breaking
change depending on interface method generation strategy and
delegating stub generation in inheriting class.
Condition was too strict if we actually make super call
through super class. Diagnostic is redundant cause there isn't breaking
change depending on interface method generation strategy.
This can happen e.g. if all supertypes were on the cycle (A : B, B : A)
-- then SupertypesLoopChecker will cut all supertypes that are on cycle,
leaving set of supertypes empty.
Some clients in the compiler are not ready to work with empty list of
supertypes -- notably, CommonSupertypes.

Treat them like lambdas. This means:
1) Like local suspend lambdas, which become "non-suspend" after creating
jvmSuspendView, they do this as well
2) They both are generated with the same codegen.
3) They are treated differently only on front-end side.

The problem is coming from the fact that `AnnotationTarget.VALUE_PARAMETER` is mapped to receiver parameter and to value parameter, but annotation with use-site target `receiver` can be used only on type reference of receiver parameter
Fixes #KT-23153 for Kotlin 1.3
The problem was in the type check of expression type against expected type. When feature `AssigningArraysToVarargsInNamedFormInAnnotations` (KT-20171) appeared, expected type could be wrong, which led to failed type check
Use fake continuation instead of ALOAD 0 while inlining
Do not generate state machine for inner lambdas and inner objects,
which capture crossinline suspend lambda.
#KT-19159: Fixed
Note, that this change potentially has some other effects in corner cases
(like the changed test data that is rather sensible because `bar`
in the example is not effectively projected out and can be called
with nulls)
Probably, we need to consider rewriting all other isSomeType methods
in KotlinBuiltins, but now it seems to be a rather dangerous change
#KT-16424 Fixed
Introdude deprecation as per KT-21515. Warning is reported on type
usage, that soon will became invisible. Quickfix by adding explicit
import is added.
Idea behind implementation is to mark scopes that are deprecated (see
ClassResolutionScopesSupport).
Then, during walk along hierarchy of scopes, look at deprecation status
of the scope that has provided this classifier.
Note that we also have to check if there are *some* non-deprecated
visibility paths (because we can see classifier by two paths, e.g. if
we've added explicit import) -- then this type reference shouldn't be
treated as deprecated.
Probably, it would be more correct to skip such lambdas when resolving
the returns' references, but it'd be more complicated and still useless
since non-local returns are impossible in such lambdas
(relevant parameter is noinline)
#KT-22900 Fixed
In an open expected class inheriting an expected interface, abstract
members are now inherited as _open_ fake overrides, not final. Final was
technically safer but also stricter and thus could be unexpected by the
user. In a final class, abstract members are still inherited as _final_
fake overrides. So, the general rule is now the following: the modality
of an expected fake override, which overrides only abstract members, in
a non-abstract class is equal to the modality of that class
#KT-22031 Fixed
This test checks that a usage inside an annotation argument is a
signature usage, which may be too restricting but easier to support at
the moment (and the restriction can be lifted in the future)
This results in more diagnostics usually, but allows library authors to
avoid annotating everything in each experimental class with the marker
(only the class needs to be annotated now)
