Supported:
- conversion in resolution parts. Also sam-with-receiver is supported automatically
- separate flag for kotlin function with java SAM as parameters
TODO:
- fix overload conflict error when function type is the same byte origin types is ordered
- consider case when parameter type is T, T <:> Runnable
- support vararg of Runnable
[NI] Turn off synthetic scope with SAM adapter functions if NI enabled
Such test has no ense in NI because NI it is LV = 1.4 and we cannot
repeat behaviour in 1.3 anyway, so I propose not even support old cases.
Also priority of LANGUAGE directive should be more then key enabled on
all tests -- also fixed.
if assertions mode is not LEGACY.
This is done since assertions can be disabled (in both compile time and
runtime) and thus, the data flow info is not reliable anymore.

If a declaration is annotated both with SinceKotlin and WasExperimental
and the SinceKotlin version makes it inaccessible, the experimental
checker must regard it as experimental, with markers specified in the
WasExperimental annotation arguments. So only errors/warnings about the
experimentality are going to be reported in this case, and no error that
the declaration is unavailable because of a low API version
For example, if a class is `@SinceKotlin("X")
@WasExperimental(M::class)`, then its constructor should also be
accessible if API < X, provided that the opt-in to M is given
Experimental and UseExperimental can only be used as annotations or
qualifiers (to allow "Experimental.Level.*"); experimental markers can
only be used as annotations or qualifiers, or as left-hand side of a
::class literal in arguments to UseExperimental/WasExperimental.
This is needed because we're not yet sure of the design of this feature
and would like to retain the possibility to drop these declarations
(Experimental, UseExperimental) altogether. If they were going to be
used as types, it would be problematic because we can't simply delete
something from stdlib, should deprecate it first. With this change,
these declarations can only be used if the user has opted into using the
experimental API somehow (for example, with
`-Xuse-experimental=kotlin.Experimental`), so we won't stop conforming
to our deprecation policy if we decide to remove these declarations in
the future
Usages of declarations annotated with WasExperimental are allowed even
if the API version requirement is not satisfied, provided that the
opt-in to all mentioned markers is given. This is needed for smooth
graduation of API in kotlin-stdlib
Since we're not yet sure of the design of Experimental/UseExperimental,
we're making them "experimental" themselves in some sense, in that the
user is required to provide the magic argument
"-Xuse-experimental=kotlin.Experimental" to be allowed to use either
Experimental or UseExperimental. This is more convenient than the
previous approach of "-language-version 1.3
-Xskip-metadata-version-check" because it's simpler and does not cause
pre-release binaries to be produced
See https://github.com/Kotlin/KEEP/issues/95#issuecomment-383889404
Drop Experimental.changesMayBreak, Experimental.Impact, the concept of
signature/body usage, same module exemption. Make the majority of tests
single-module because there is now no difference in the checker between
usages from the same module or from another module
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.
