Issue 12928 - Range check dropped for array[length]

IntRanges in DMD are inclusive. The range check would get dropped if the expression for the index was contained within [0..length]-inclusive. This would drop the range check for [length].

Default compiler switch permutation for runnable cases is `-inline -release -g -O`, so `PERMUTE_ARGS: -inline -g -O` is more better.
