Ramkumar Ramachandra f1eed011b4 MathExtras: add overflow query for signed-div (#97901)
5221634 (Do not trigger UB during AffineExpr parsing) noticed that
divideCeilSigned and divideFloorSigned would overflow when Numerator =
INT_MIN, and Denominator = -1. This observation has already been made by
DynamicAPInt, and it has code to check this. To avoid checks in multiple
callers, centralize this query in MathExtras, and change
divideCeilSigned/divideFloorSigned to assert on overflow.
