[-Wunsafe-buffer-usage] Fix false warnings when const sized array is safely accessed (array [idx %const]) (#140113)
The -Wunsafe-buffer-usage analysis currently warns when a const sized
array is safely accessed, with an index that is bound by the remainder
operator. The false alarm is now suppressed.
Example:
int circular_buffer(int array[10], uint idx) {
return array[idx %10]; // Safe operation
}
