  When enabled, duk_hstring stores a precomputed array index (or "not an array
  index") value related to the string.  This reduces code footprint and
  improves performance a littl ebit.

  When disabled, duk_hstring has a flag indicating whether it is an array
  index or not, but the actual value is computed on-the-fly.
