2010-09-15  Tejas Belagod  <tejas.belagod@arm.com>

        * config/arm/neon.md (vec_pack_trunc_<mode>): Instruction
        pattern for vmovn. Expansion in case of non 
        -mvectorize-with-neon-quad.
        (neon_vec_pack_trunc_<mode>): Instruction pattern for vmovn for
        non- -mvectorize-with-neon-quad case.
        (move_lo_quad_<mode>): New expansion to vmov into low part.
        (move_hi_quad_<mode>): New expansion to vmov into high part.
        (move_lo_quad_v4si): Refactor to move_lo_quad_<mode> expansion.
        (move_lo_quad_v4sf): Likewise.
        (move_lo_quad_v8hi): Likewise.
        (neon_move_lo_quad_<mode>): Instruction pattern for vmov into
        low part.
        (neon_move_hi_quad_<mode>): Instruction pattern for vmov into
        high part.
        * config/arm/iterators.md (ANY128): New mode iterator.
        (V_narrow_pack): New mode attribute.
        (V_HALF): Add attribute.
        (V_DOUBLE): Add attribute.
        (V_mode_nunits): Add attribute.
