[ARM] PR 68149 Fix ICE in unaligned_loaddi split

PR target/68149
* config/arm/arm.md (unaligned_loaddi): Delete.
(unaligned_storedi): Likewise.
* config/arm/arm.c (gen_movmem_ldrd_strd): Don't generate
unaligned DImode memory ops.  Instead perform two back-to-back
unaligned SImode ops.

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

It's a regression on this particular testcase for GCC 6, but I don't know how
old the latent bug is
