[legalize-types] Remove stale entries from SoftenedFloats.
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.
