Just to note that on master it was necessary to apply r12-3480 as part of a
subsequent patch set.  The problem case was calling gen_highpart() on an
unaligned MEM.  Prior to this patch gen_highpart() would generate the expected
unaligned MEM for the narrower access, but after r12-163 we'd get (subreg(MEM))
being returned, which was unexpected.  I'm not going to backport that now as
it's not clear if this is needed for GCC-11.
