Synopsis:
    #include <mmintrin.h>
    __m64 _m_pslld(__m64 *m, __m64 *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"
    #define AS_QWORD "%16.16Lx"

    __m64   a;
    __m64   b = { 0x3f04800300020001 };
    __m64   c = { 0x0000000000000002 };

    void main()
      {
        a = _m_pslld( b, c );
        printf( "m1="AS_DWORDS"\n"
                "m2="AS_QWORD"\n"
                "mm="AS_DWORDS"\n",
            b._32[1], b._32[0],
            c,
            a._32[1], a._32[0] );
      }

    produces the following:

    m1=3f048003 00020001
    m2=0000000000000002
    mm=fc12000c 00080004
