Implement small object optimization in swisstable - disabled for now.
Details:
- We use the space for control/slots pointers as the inline buffer.
- We use a max inline capacity of 1 to make the implementation much simpler and to avoid having to randomize the iteration order for inline tables.
- For iteration of inline tables, we introduce the kSooControl buffer which just has 1 full control byte followed by 1 sentinel control byte so that incrementing yields an end() iterator. We don't access kSooControl during lookups - only iteration.
