Damien Neil 170b2bfca6 internal/impl: precompute required bit in validator 
Required field validation populates a bitmask of observed required
fields. Store a uint64 containing the bit to set in the validationInfo
rather than the index of the bit. Provides a noticeable speed increase
in validation.

Next Generation Go Protocol Buffers

WARNING: This repository is in active development. There are no guarantees about API stability. Breaking changes will occur until a stable release is made and announced.

This repository is for the development of the next major Go implementation of protocol buffers. This library makes breaking API changes relative to the existing Go protobuf library. Of particular note, this API aims to make protobuf reflection a first-class feature of the API and implements the protobuf ecosystem in terms of reflection.
