Fix stdlib compilation after updated @JvmName check

Previously, extension receiver type was not taken into account when
checking for @JvmName annotation applicability to possibly mangled
functions (such functions, however, were mangled).
This bug was fixed, but, unfortunately, not before such functions were
added to stdlib ('sumOf' family).
