Denis.Zharkov b6b132a9a3 K2: Avoid false-positive overload resolution ambiguity with smart casts
The idea is that when we have successful candidates both from smart cast
and original type, we should discriminate in the favor of former ones.

While this problem (see kt55722.kt) existed before this branch is merged,
initially it was recognized on FP Ultimate when we stopped assuming
captured types from the same projections as equal (see kt55722Initial.kt).
