Reviewers: Michael Starzinger,
Description:
[turbofan] Fix lowering of typed loads/stores.
We can only access to external typed arrays; lowering of internal
typed arrays would require a map check plus eager deoptimization.
Also embed the backing store reference directly instead of embedding
the typed array and then loading the backing store from its buffer.
