src/ic.cc:1426: if (target_receiver_maps.length() == 0) {
length() == 0 isn't the same as UNINITIALIZED || PREMONOMORPHIC. We
could also have length() == 0 if for some reason there's an instance
type check rather than a map-check. With your change we'd go monomorphic
where otherwise we would've gone generic. (See the comment below that
you removed).
I presume we'd actually need to introduce something similar for load,
rather than remove it for the store.
