Function safe_arch::test_mixed_ones_and_zeroes_m128i

pub fn test_mixed_ones_and_zeroes_m128i(a: m128i, mask: m128i) -> i32

Returns if, among the masked bits, there’s both 0s and 1s

• Zero Flag = (a & mask) as u128 == 0
• Carry Flag = ((!a) & mask) as u128 == 0
• Return ZeroFlag == 0 && Carry Flag == 0
