The previous commit improves the precision in scalar(32)_min_max_add, and scalar(32)_min_max_sub. The improvement in precision occurs in cases when all outcomes overflow or underflow, respectively. This commit adds selftests that exercise those cases. This commit also adds selftests for cases where the output register state bounds for u(32)_min/u(32)_max are conservatively set to unbounded (when there is partial overflow or underflow).
