Synopsis:
    #include <mmintrin.h>
    __m64 _m_pslldi(__m64 *m, int count);

Description:
    The 32-bit double-words in m are each independently shifted to the left
    by the scalar shift count in count.  The low-order bits of each element
    are filled with zeros.  The shift count is interpreted as unsigned.
     Shift counts greater than 31 yield all zeros.

Returns:
    Shift left each 32-bit double-word in m by an amount specified in count
    while shifting in zeros.

Example:
    #include <stdio.h>
    #include <mmintrin.h>

    #define AS_DWORDS "%8.8lx %8.8lx"

    __m64   a;
    __m64   b = { 0x3f04800300020001 };

    void main()
      {
        a = _m_pslldi( b, 2 );
        printf( "m ="AS_DWORDS"\n"
                "mm="AS_DWORDS"\n",
            b._32[1], b._32[0],
            a._32[1], a._32[0] );
      }

    produces the following:

    m =3f048003 00020001
    mm=fc12000c 00080004
