It looks like the patterns all look for 32-i as the second shift amount.
Writing an additional version that takes a constant (with an extra check that
the sum of the constants is 32, and we then have to specify immediate_length
manually) and replacing (match_dup 0) with an extra operand that has the
constraint "0" seems to work. (and breaks again if I swap the 2 sides of
operator| )
