Nit: please make this change in your new CL.

Move this definition to line 98, before the "// Server hello tags" line, and
change this to:

// Rejection tags
const QuicTag kRREJ = TAG('R', 'R', 'E', 'J');   // Reasons for server sending
                                                 // rejection message tag.

Fixed in CL: https://codereview.chromium.org/336273006/

Done.

 // These tags have a special form so that they appear either at the beginning
 // or the end of a handshake message. Since handshake messages are sorted by
 // tag value, the tags with 0 at the end will sort first and those with 255 at
 // the end will sort last.
 //
 // The certificate chain should have a tag that will cause it to be sorted at
 // the end of any handshake messages because it's likely to be large and the
 // client might be able to get everything that it needs from the small values at
 // the beginning.
