*
     * @param receiverExpression a qualified expression receiver (e.g., `foo` in `foo?.bar()`, or in `foo.bar`).
     *
     * The function unwraps certain receiver expressions. For instance, for safe calls direct counterpart to a [KtSafeQualifiedExpression]
     * is (FirCheckedSafeCallSubject)[org.jetbrains.kotlin.fir.expressions.FirCheckedSafeCallSubject] which requires additional unwrapping
     * to be used for call resolution.
