Peter Marshall 23c4288380 [typedarray] Add a fast-path copy of arrays in IterableToList 
Currently we perform the full iteration protocol even when we don't need
to. When IterableToListCanBeElided is true, we still need to create a
copy of the array (from a spec correctness point of view, in case there
are user-JS side-effects that would modify the original).

This CL copies the array directly, skipping the iteration protocol.
This recovers the JSTests/TypedArrays/ConstructArrayLike benchmark
almost completely.
