# Initially %2 starts out with 2 subranges (one for sub0, and one for
# the rest of the lanes). After %2 is split, after refineSubRanges the
# newly created register has a different set of lane masks since the
# copy bundle uses 2 different defs to cover the register. This was
# fixed by doing refineSubRanges after all the COPYs being inserted.
