[IRCE] Implement runtime overflow check for computed range's end

Here is activated check elimination which was parsed previously in
https://reviews.llvm.org/D154069

* Added runtime check that computed range's boundary doesn't overflow in
terms of range type.

* From the statement INT_MIN <= END <= INT_MAX is inferred check:
isNonNegative(INT_MAX - END) * isNonNegative(END - INT_MIN).

* If overflow happens, check will return 0 and the safe interval will be
empty.
