This is a reland of commit d00c040547
Changes since revert: Use AsAtomicTagged instead of
base::AsAtomicPointer to store a hash value in the forwarding table.
Original change's description:
> [strings] Support shared external strings>
>
> With this CL shared strings can be externalized and external strings can
> be shared.
> The StringForwardingTable is used to delay the real transition to the
> next full GC. On the API side strings marked for externalization will
> look like externalized strings.
