[PATCH] [ARM] Fix PR57909 : ICE with internal memcpy and -mno-unaligned-access

[Yvan Roux]

Hi,

this patch fixes the issue described in PR57909, where we have an ICE
during the internal memcpy, as some UNSPEC_UNALIGNED insns are emitted
even if -mno-unaligned-access flag is passed. See the link below for a
more detailled description:

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=57909

Tested without any regression.

Thanks,
Yvan
