/* Assuming TYPE is a simple, non-empty array type, compute its upper
and lower bound. Save the low bound into LOW_BOUND if not NULL.
Save the high bound into HIGH_BOUND if not NULL.
Return 1 if the operation was successful. Return zero otherwise,
in which case the values of LOW_BOUND and HIGH_BOUNDS are unmodified.
We now simply use get_discrete_bounds call to get the values
of the low and high bounds.
get_discrete_bounds can return three values:
1, meaning that index is a range,
0, meaning that index is a discrete type,
or -1 for failure. */
