Fix handling of null arrays when calculating the secondary stack size
for the binder.
gcc/ada/
* sem_util.adb (Number_Of_Elements_In_Array): Fix counting of
elements in null arrays; remove redundant parenthesis; avoid
run-time conversion of 1 to universal integer.
Tested on x86_64-pc-linux-gnu, committed on master.
