Comment (by Niklas Haas):

 Looking at it some more, it appears to be a regression. The patch in
 question is definitely not correct as-is. The condition was made overly
 broad, and in retrospect, is probably unnecessary.

 I will investigate some more; in particular we need to make sure that the
 unscaled float_y_to_uint_y wrapper works as intended. But if that already
 works on master, that patch should probably just be dropped.
