x86: Convert integer constant to mode of move

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.
