Michael Pratt 808da68c1c internal/runtime/maps: linear scan of small map 
We still use the hash and control word, but loop over all 8 bytes
instead of doing the match operation, which ends up being slightly
faster when there is only one group.

Note that specialized variants added later will avoid hashing at all.

For #54766.
