[turbofan] Funnel class constructors through TurboFan.

Browse Source 
This makes optimization of all class constructors (i.e. both base and
derived) go through TurboFan. Note some class constructors containing
Harmony language features (e.g. super constructor calls or accesses to
the new.target value) were already going through TurboFan before.
