i386: Emulate MMX vec_dupv2si with SSE

Emulate MMX vec_dupv2si with SSE.  Add the "Yw" constraint to allow
broadcast from integer register for AVX512BW with TARGET_AVX512VL.
Only SSE register source operand is allowed.

PR target/89021
* config/i386/constraints.md (Yw): New constraint.
* config/i386/mmx.md (*vec_dupv2si): Changed to
define_insn_and_split and also allow TARGET_MMX_WITH_SSE to
support SSE emulation.
