See 62a55b7b00
Previously, it was working for O(n^2)
Now, we first group it by jvm descriptor,
then for each groups of size g_i finding the most specific for O(g_i^2)
It should help for the cases when we have a lot of overloads with
different JVM descriptors (modulo return type)
NB: Having the same JVM descriptors is rather rare, because
in Java one cannot generate such a class.
Looks like it's only possible for Scala or some other JVM languages (KT-17560)
It should help a lot for KT-35135
