The way runtime/platform/hashmap.h:HashMap was implemented so far did not allow
deleting elements while iterating over the map. If one iterated like this
HashMap::Entry* cursor = map.Start();
while (cursor != NULL) {
if (cond) {
map.Remove(cursor->key, cursor->hash);
}
cursor = map.Next(cursor);
}
Then the iteration `cursor` will skip elements. This is due to the fact that
`HashMap::Remove()` is left-rotating elements in certain cases and
`HashMap::Next()` will unconditionally advance to the next position in the
backing store.
PROBLEM IS: There was existing code which did remove elements while iterating
over a HashMap.
