internal/impl: omit isInit func when not needed

When generating the fast-path functions for a message, group, repeated
message, or repeated group field, check to see if the field message type
requires initialization checks. If not, leave the isInit func unset.

This permits the fast-path isInitialized to skip over these fields
entirely.

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.
