Move FixedIdentitySet off the Array hierarchy.
Provide a fast implementation using MethodDictionary tricks
- handles collisions (instead of blindly ignoring the entry)
- eventually grow.

I did not understand previous design decision...
The conflict just did happen (I put a halt: and caught one in Object...)
According to my own scale, make it work > make it fast.

Rationale about the new design:
#grow costs, but I think it is user responsibility to fix a reasonnable capacity.
collisions handling should not cost much (except above 4096 entries)

If any expert knowing the reasons for this class and knowing how to fire the profiling tests could have a look, thanks...
