Damien Neil 3d0706ac2e proto, internal/impl: make IsInitialized more consistent
Make the fast-path and slow-path versions of IsInitialized report
exactly the same errors: An errors.RequiredNotSet containing the
full name of one of the unset required fields.

Bugfix: Fast-path IsInitialized on a nil message reports an error only
when the message directly contains required fields.

Bugfix: Include fast-path IsInitialized in legacy messageIfaceWrapper.

Fixes golang/protobuf#887
