Just a heads up - FullCodeGenerator::VisitClassLiteral is now dead code since
any code which is unsupported by Crankshaft is now only ever executed in
Ignition+TurboFan (not FCG), so no need to add / port this code. We will get
round to ripping out the existing class literal code soon (see
https://bugs.chromium.org/p/v8/issues/detail?id=5657).
