* When storing a zero-bit type, we should short-circuit almost
  immediately. Zero-bit stores do not need to do any work.
* The bit size computation for arrays is incorrect; the `abiSize` will
  already be appropriately aligned, but the logic to do so here
  incorrectly assumes that zero-bit types have an alignment of 0. They
  don't; their alignment is 1.
