Also move internal declarations from runtime.jvm module into new package
kotlin.coroutines.jvm.internal in stdlib
The necessity of these declarations being in built-ins is controversial,
but also it will complicate the migration of current coroutine runtime
to a separate jar if we ever need this
- move getDelegates from CodegenUtil to DelegationResolver, reuse it in
DelegationChecker
- use getAllOverriddenDescriptors + filterOutOverridden instead of a manual DFS
This may be more correct in case of complex cross-module inheritance, where
overridability should be detected by structural equality of signatures instead
of referential equality of constructed descriptors (no test added because it's
not so easy to come up with an example)
To simplify migration from 1.0 to 1.1, do not allow data classes to
automatically implement abstract equals/hashCode/toString declared in
super-interfaces (KT-11306) if "-language-version 1.0" is specified
Change getAllOverriddenDescriptors contracti, now it returns
original (not substituted) descriptors without any duplicates.
First of all it's necessary in CodegenUtil.getDelegates to avoid
duplicates (see assertion there), but also it's convenient for all
other usages of this method
#KT-8154 Fixed
- change prerequisites for generating equals/hashCode/toString in a data class:
previously they were generated if the corresponding method is trivial (i.e.
it comes from kotlin.Any), now we're generating it always unless it'll cause
a JVM signature clash error (see KT-6206)
- use static KotlinBuiltIns.isXxx methods to compare types instead of checking
against descriptors loaded from certain built-ins instance, this is quicker
and more correct in environments where several built-ins are possible
- don't use isOrOverridesSynthesized, it's not relevant for
equals/hashCode/toString because functions with these names are never
synthesized
#KT-6206 Fixed
- report errors on implementing methods of Any in interfaces
- update testData
~~~
Java 8 override restrictions: interface can't implement a method of 'Any'
- update compiler sources
