i386.md (prefetch): Rename as prefetch_sse to avoid conflicts with new generic prefetch functionality.

	* config/i386/i386.md (prefetch): Rename as prefetch_sse to avoid
	  conflicts with new generic prefetch functionality.
	* config/i386/i386.c (ix86_expand_builtin): Use new name for
	  prefetch_sse.
