Alternatively, we could improve the lookup utilities and their usages to always find the exact override of a symbol from Collection/Iterable/CharSequence/etc, but since we need to load the original symbol anyway in cases when the loop subject's type is a type parameter, we might as well simplify everything and always reference the original symbol. Also improve exception message and removed unused declarations in IrBackendUtils.kt.
