Marja Hölttä b1553b9188 [interpreter] Omit calling default ctors 
If we see a default ctor, walk up the constructors until we find a non-
default one.

Default ctors can only be skipped if there are no class fields / private
brands.

This CL implements the Ignition parts; Sparkplug, Maglev and TF will
be implemented as follow ups. (This is fine, since this feature is
behind a flag.)
