Summary: When replacing a SDValue, we should remove the replaced value from SoftenedFloats (and possibly the other maps as well?). When we revisit a Node because it needs analyzing again, we have to remove all result values from SoftenedFloats (and possibly other maps?). This fixes the fp128 test failures with expensive checks for X86. I think we probably should also remove the values from the other maps (PromotedIntegers and so on), let me know what you think.
