[PATCH i386 AVX512] [67/n] Update constraints in vec_dup insn pattern.

[Kirill Yukhin]

Hello,
This tiny patch updates constraints in vec_dup insn
pattern.

Bootstrapped.
AVX-512* tests on top of patch-set all pass
under simulator.

Is it ok for trunk?

gcc/
        * config/i386/sse.md
        (define_insn "vec_dup<mode>"): Update constraints.

Thanks, K
