--- Comment #2 from ktkachov at gcc dot gnu.org ---
Seems that the unaligned_loaddi splitter was just added as a helper for
gen_movmem_ldrd_strd to try to emulate DImode unaligned loads when expanding
movmems.
I'm testing a fix that involves removint he unaligned_loaddi and
unaligned_storedi altogether and instead doing the right thing on unaligned
movmems directly inside gen_movmem_ldrd_strd
