... when deserializing. EphemeronHashTables require valid HeapObject keys, however EphemeronHashTables are filled with Smi::uninitialized_deserialization_value when deserializing. We could fill EphemeronHashTable's elements with "the initial filler" which is undefined value to make sure the elements are valid.

This is a reland of commit 40901824 The reason for revert was regressions in `blink_gc:effective_size` buckets of `system_health.memory_desktop` benchmarks. See http://crbug/1356329#c51. Memory Perf Sheriffs: This CL shifts GC times which regresses `blink_gc:effective_size` but improves `v8:effective_size` bucket by a similar amount. The `private_footprint_size` metric stays neutral for the majority of the stories and for certain load stories it even improves.

Shared values need to be kept alive while being conveyed across threads (i.e. by postMessage). Currently they are meant to be conveyed through the serializer/deserializer by the embedder via API. This both clunky and the embedder has no good choice for what to do, because the most natural choice is v8::Global and it is not designed to be threadsafe. This CL removes the API and transparently handles conveying shared values by using a wrapper around PersistentHandles called SharedValueConveyors. Any isolate can own the conveyor provided it outlives the receipt of the message by the receiving isolate. For simpler lifetime management, the shared isolate currently owns all conveyors.

For code pointers, the sandbox will require a custom, lightweight CFI mechanism (likely based on the external pointer table). Simply turning all code pointers into ExternalPointers is not sufficient.

The fields moved in the IsolateData: - is_marking_flag and is_minor_marking_flag (checked by write barriers) - is_profiling (checked on API callbacks/getter calls) - stack_is_iterable (not super hot, checked during deoptimization). Drive-by: this CL defines the bool fields as uint8_t in order to make the field size expectations clear.
