Bill Wendling 32e4544198 Use the 'count' attribute to calculate the upper bound of an array.
The count attribute is more accurate with regards to the size of an array. It
also obviates the upper bound attribute in the subrange. We can also better
handle an unbound array by setting the count to -1 instead of the lower bound to
1 and upper bound to 0.
