Benedikt Meurer 523be745d2 [turbofan] Properly handle -0 in Word32->Word64 conversion. 
This adds missing support when converting a Word32 value (either in
Signed32 or Unsigned32 range) to Word64 representation, for which the
type also includes MinusZero. This conversion is fine as long as the
difference between 0 and -0 is not observable (in other words, as long
as the truncation identifies zeros).
