In order to support compiling to baseline on return we need to be able to
return to the actual return address. With this change this is what the
Return bytecode now does, removing the need for the
InterpreterExitTrampoline.
This change also removes the InterpreterNotifyDeoptXXX builtins and
unifies FCG and Igntion to both use NotifyDeoptXXX. As part of this
change, FullCodegenerator::State is moved to Deoptimize::BailoutState.
