I strongly disagree with this sentiment. This patch fixes one particular issue (dead code elimination) with 1 particular kind of operation (floating-point remainder, which is IMO a really niche operation). This patch does not fix other issues (GVN, scheduling, floating-point remainder alters memory unnecessarily, etc) or does not fix the issue with other similar operations. I don't think the benefits justify adding this band-aid.
