[Bug target/38736] New: [4.4 Regression] -mavx can change the ABI via BIGGEST_ALIGNMENT

["pinskia at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

using __attribute__((aligned)) can change the alignment dependent on if you use
-mavx or not.
This is because BIGGEST_ALIGNMENT is defined using -mavx.  This is not correct
as -mavx should not change the ABI unless you use the avx sized vectors.
