Modification registration seems to changed in Java 9. Now if the asked
capacity in `ensureCapacity` function is less than current capacity,
no modification is registered.
Sequence::toSet and Sequence::toList both create a
collection, fill it with elements, and then try to optimize a result
by returning empty, singleton, or the allocated collection depending on
the elements count.
Instead of allocating the collection and then trying to return
an optimized instance it is worth checking the sequence's size
beforehand and return empty/singleton collection when possible.
Proposed change optimize performance of aforementioned functions and
also reduce allocation rate when a sequence consists of 0 or 1 elements.
^KT-55091 fixed
Improve the performance of reversed list view iterators by delegating to
underlying list iterators instead of using implementations provided by
the AbstractList.
Latter use AbstractList::get(index: Int) to implement next() and
previous() methods and depending on the underlying list's implementation
it may lead to worse performance.
The change also improves reversed list views test coverage.
* Provide short-circuit methods for contract "EnumEntries contains all
enum entries"
* Make EnumEntries serializable
* Introduce more convenient overload for other backends

If the collection of elements to be added is empty, java6 implementation
of AbstractMutableList.addAll doesn't throw on invalid index.
The failing test was introduced in 59031543e2
which fixed #KT-47211.
- Int.toChar was left non-deprecated because the replacement is not intrinsic yet.
- Number.toChar was left non-deprecated because otherwise the deprecation propagates to the override, Int.toChar.

This is a workaround for the problem KT-43321.
Introduce an intermediate abstract set specialized for Map.Entry elements
and implement 'contains(Map.Entry)' method there.
Then inherit that intermediate set in entrysets of JS HashMap,
JS LinkedHashMap, JVM MapBuilder, that are specialized for
MutableMap.MutableEntry elements, so that no override of 'contains' is
required anymore.
This allows to avoid incorrect special 'contains' bridge being generated
that otherwise rejects all arguments except ones of MutableEntry type.
The error SIGNED_CONSTANT_CONVERTED_TO_UNSIGNED is suppressed in this
file, and JVM IR is not able to generate comparisons of UInt and Long
(KT-41780).
