 Description   

This is done as part of BSON key generation (with empty field names), which is on a hot code path. This results in a surprising 10% speedup of validate.

Something must have gone wrong in my initial measurements. I can only reproduce at most 1% improvement, which is not sufficient to warrant this change. For master we'll be switching to encoding KeyString directly which is a far larger benefit, so closing this ticket as won't fix.
