X87: [crankshaft] Loads and stores to typed arrays have to reference the backing store holder.

  port 086d4598473fe25b6b8f802998d6e85e90625136 (r32644)

  original commit message:
  The backing store is only held alive indirectly via the array buffer
  referenced by the holder (typed array), so it's not enough to keep the
  elements alive (or even just the external pointer loaded from the
  elements).
