[Patch, AArch64]: Fix test harness to for unaligned vector mem access.

[Tejas Belagod]

Hi,

Currently on the trunk, we have many vect tests that fail for aarch64-*-*
because check_effective_target_vect_no_align () in target-supports.exp returns
true for aarch64 where in fact it should be returning false. This causes the
tests that check for vect_no_align and expect messages for loop versioning to
fail. The attached patch drops aarch64 from the list of targets in
check_effective_target_vect_no_align () as unaligned access is supported.

Tested on trunk for aarch64-none-elf with no regressions. OK for trunk?

Thanks,
Tejas Belagod
ARM.
