Tests on x86 might fail, possibly due to a 16-bit sub overflow
If this only happens in checkasm but not in real life use, it means that the checkasm test input is out of range, and we should try to mimic the real input data.
If the issue is off-by-one due to rounding, we could allow it by making a comparison per element, and tolerate a certain diff (maybe only on x86).
But if it is an actual overflow on valid input data, the x86 asm definitely needs to be fixed, by someone... Worst case, we might want to disable that checkasm test on x86 temporarily.
