    Make DECLARE_ALIGNED_8 align to 8 bytes, never to 16
    
    The DECLARE_ALIGNED_8 macro is defined to align to 16 bytes instead
    the 8 suggested by the name on some CPUs.  None of the uses of this
    macro ever need 16-byte alignment, cases which once did having been
    changed to always specify 16 bytes explicitly.
