x86: Add vec_duplicate<mode> expander

Add vec_duplicate<mode> expander for SSE2 if we can move from GPR to SSE
register directly.

* config/i386/i386-expand.c (ix86_expand_vector_init_duplicate):
Make it global.
* config/i386/i386-protos.h (ix86_expand_vector_init_duplicate):
New prototype.
* config/i386/sse.md (INT_BROADCAST_MODE): New mode iterator.
(vec_duplicate<mode>): New expander.
