[Bug target/14552] compiled trivial vector intrinsic code is inefficient

gcc-3.3.6 produces better code:

test:   movq    w, %mm1
        psllw   $1, %mm1
        movq    %mm1, w
        movq    w, %mm1
        movq    %mm1, dw
        ret

        .comm   dw,8,8
        .comm   w,8,8


can we classify this as a code size regression?
