port d3e5db04 (r32336)

  original commit message:
  Up until now we sometimes pass Smi 0 around as closure and expect the
  runtime to translate that appropriately. But we need to be careful in
  some places to not confuse the Smi 0 with a real closure. However, we
  could instead just pass the correct closure extracted from the native
  context.

  This addresses three long-standing TODOs in the JSTypedLowering pass.

  Drive-by-fix: Further unify error message reporting for ToObject (we had
  a special message in case of ToObject error in with context creation).
