Report for improved id_table implementation

• it has up to 25% less size (19% on smallest tables)

• it is a bit slower on small tables (~3%) for hit and a bit faster for miss

• due to additional mix of key bits, it is always faster on big tables.

  Note: bit mixing makes small tables slower, so it is enabled only for big tables (>64 capacity).

  If performance for small tables much more important, mixing could be removed completely (this will return 1% on hit)
