Remove the ArrayDeque.subList().subList() test for comodification detection.
For types that extend AbstractList and to not override subList function,
the behavior varies depending on JDK version. With JKD8, the test fails for ArrayDeque.
While with JDK9+, it passes.
Test ArrayDeque with size 15. With the existing sizes the removeRange
implementation couldn't reach the maximum number of iterations - 3.
Benchmark results for ArrayDeque.subList().clear() that uses
removeRange() can be found here:

At the moment, SubclassOptInRequired is marked with the
ExperimentalSubclassOptIn annotation. However, it does not work
as expected due to a missing opt-in error. To use SubclassOptInRequired,
an explicit opt-in is necessary because SubclassOptInRequired is an
unstable feature now.

I blindly converted all `@AllowDifferentMembersInActual` to suppresses.
But some suppresses in stdlib are redundant. I'm too lazy properly
annotate only the necessary places. All these suppresses will go away
after the bootstrap update anyway
I drop allowDifferentMembersInActual_class and
allowDifferentMembersInActual_typealias tests because their only purpose
was to check that `@AllowDifferentMembersInActual` works as expected
Note: some tests are failing in the compiler because of that. I will fix
them in the next commit
Rewrite FlatteningSequence to use
the same optimization technique as AbstractIterator.
Didn't extend AbstractIterator as storing and reloading a value
from a field is slightly slower compared to the implemented approach.
Use integer constants instead of enum to track AbstractIterator's state:
- for switches with a few cases, integer constants are
faster as there's no need to load ordinal value from
enum and map it into tableswitch index;
- on JVM, JIT-compiler can optimize away state-tracking code if it uses
integer constants, but when it comes to enums and tableswitches,
it can't apply a same set of optimizations to it.
It is implemented in JVM, JS and Native backends already

Provide an inefficient default implementation and make it "@PublishedApi internal" so it can be safely merged as is.
Intrinsics will be added later in follow-up PRs, and then the implementation will be adjusted accordingly

* Also, mention implementation details of EnumEntries to enable safe uses of a 'EnumEntries' as a set
* Fix testdata for opt-in marker in enum entries
