Jelle Raaijmakers 954d660094 AK: Clear OrderedHashTable previous/next pointers on removal ...

With Clang, the previous/next pointers in buckets of an
`OrderedHashTable` are not cleared when a bucket is being shifted up as
a result of a removed bucket. As a result, an unfortunate pointer mixup
could lead to an infinite loop in the `HashTable` iterator, which was
exposed in `HashMap::keys()`.
