Name: Collections-ar.183
Ancestors: Collections-ul.179, Collections-ul.180, Collections-ul.181, Collections-ul.182

Merging Collections-ul.179, Collections-ul.180, Collections-ul.181, Collections-ul.182:

- added: String >> #hashWithInitialHash: which lets the string to decide which hash implementation to use, this way ByteStrings can use the primitive implementation instead of the general one

- speed up mergesort for the general case (using <= for comparison), sacrificing &lt; 1% performance for other cases
- allow symbols to be evaluated as comparison blocks. For example: sorting an Array in descening order can be as simple as: array sort: #>=, it's also faster than using a block.

- simplified Dictionary >> #keysSortedSafely
- simplified WeakRegistry >> #keys
- save a few bytecodes in #scanFor: of identity based collections when their size is between 4097 and 8191

- fix: WeakKeyDictionary >> #finalizeValues: (increment the tally, and make sure that we don't lose the key)
- collect the objects which should be finalized into an IdentitySet instead of an OrderedCollection in WeakRegistry >> #finalizeValues this should give better performance in WeakKeyDictionary >> #finalizeValues:
