duplicate_insn_chain accepts rtx_insn 

gcc/
2014-08-26  David Malcolm  <dmalcolm@redhat.com>

	* rtl.h (duplicate_insn_chain): Strengthen both params from rtx to
	rtx_insn *.
	* cfgrtl.c (duplicate_insn_chain): Likewise for  params "from",
	"to" and locals "insn", "next", "copy".  Remove now-redundant
	checked cast.
