// This class is an abstraction layer around initialization of components
// that are either deserialized from the snapshot or generated from scratch.
// Currently this includes builtins and interpreter bytecode handlers.
// There are two implementations to choose from at link time:
// - setup-isolate-deserialize.cc: always loads things from snapshot.
// - setup-isolate-full.cc: loads from snapshot or bootstraps from scratch,
//                          controlled by the |create_heap_objects| flag.
// For testing, the implementation in setup-isolate-for-tests.cc can be chosen
// to force the behavior of setup-isolate-full.cc at runtime.
//
// The actual implementations of generation of builtins and handlers is in
// setup-builtins-internal.cc and setup-interpreter-internal.cc, and is
// linked in by the latter two Delegate implementations.
