re PR sanitizer/63697 (-fsanitize=undefined doesn't detect some subtraction overflows)
PR sanitizer/63697
* tree-vrp.c (simplify_internal_call_using_ranges): For subcode ==
MINUS_EXPR, check overflow on vr0.min - vr1.max and vr0.max - vr1.min
instead of vr0.min - vr1.min and vr0.max - vr1.max.
* c-c++-common/ubsan/overflow-sub-3.c: New test.
