Remove "Making V&...".

Reference and const reference are totally two different types, and it shouldn't
surprise anyone if they are incompatible.

Done.

[Peter Kasting, 2016/11/10 06:41:07]

Nit: Perhaps we should do something like:

#define VISIT_PROTO_FIELDS(proto) \
template <class V> \
void VisitProtoFields(V& visitor, proto)  // NOLINT(runtime/references)

...

VISIT_PROTO_FIELDS(const sync_pb::EncryptedData& proto) {
  ...

This avoids the nasty NOLINTs in most places and makes the file shorter to boot.

(Might not even need the NOLINT now, I dunno.)

[ltian, 2016/11/11 03:52:13]

This is a more decent solution! Thanks!
