    x86: Convert integer constant to mode of move

    For

    (set (reg/v:DI 106 [ k ])
         (const_int 3000000000 [0xb2d05e00]))
    ...
    (set (reg:V4SI 115 [ _13 ])
         (vec_duplicate:V4SI (subreg:SI (reg/v:DI 106 [ k ]) 0)))
    ...
    (set (reg:V2SI 118 [ _9 ])
         (vec_duplicate:V2SI (subreg:SI (reg/v:DI 106 [ k ]) 0)))

    we should generate

    (set (reg:SI 125)
         (const_int -1294967296 [0xffffffffb2d05e00]))
    (set (reg:V4SI 124)
         (vec_duplicate:V4SI (reg:VSI 125))
    ...
    (set (reg:V4SI 115 [ _13 ])
         (reg:V4SI 124)
    ...
    (set (reg:V2SI 118 [ _9 ])
         (subreg:V2SI (reg:V4SI 124))

    by converting integer constant to mode of move.
