[x86] avoid adc/sbb assert when both sides of add are zexted (PR32316)
As noted in the comment, we might want to account for this case,
but I didn't look at what that would mean for the asm.
I'm also not sure why this only reproduces with avx512, but I'm
putting a conservative fix in for now to avoid the crash.
Also, if both sides of an add are zexted, shouldn't we shrink that add?
