Confirmed.
I'm a bit wary of just truncating the value. Shifts by 32 may be valid in the
ARM back-end in some circumstances where we're using the shift as part of
setting up the flags.
Fixing this fully would require getting rid of "shift_operator" and replacing
it with iterators. But that's a pretty radical overhaul. Long term that might
well be worthwhile, but not this close to a release.
