      Description

      The asm vsns of pd_disjoint_words and pd_conjoint_words are not optimised for unaligned accesses.

      Some partners' HW has large penalties for unaligned accesses.

      This issue proposes opimising pd_disjoint_words and pd_conjoint_words for unaligned access.

      Performance on platforms which support unaligned accesses without penalty should not be affected by this change.
