find_first_parameter_load returns an rtx_insn 

2014-08-21  David Malcolm  <dmalcolm@redhat.com>

	* rtl.h (find_first_parameter_load): Strengthen return type from
	rtx to rtx_insn *.
	* rtlanal.c (find_first_parameter_load): Strengthen return type
	from rtx to rtx_insn *.  Add checked cast for now, to postpone
	strengthening the params.
