Make TRUE/FALSE edge calculation available without the outgoing edge class.

Rename class to gimple_outoging_edge and provide a non-class routine for
the outgoing edge of a gcond.

	* gimple-range-edge.h (gimple_outgoing_range): Rename from
	outgoing_range.
	(gcond_edge_range): Export prototype.
	* gimple-range-edge.cc (gcond_edge_range): New.
	(gimple_outgoing_range::edge_range_p): Use gcond_edge_range.
	* gimple-range-gori.h (gori_compute): Use gimple_outgoing_range.
