Log:
	* tree-ssa-threadedge.c (thread_across_edge): Record entire path
	when not threading through a joiner block.  Pass joiner/no joiner
	state to register_jump_thread.
	* tree-ssa-threadupdate.c (register_jump_thread): Get joiner/no joiner
	state from argument rather than implying on path length.
	Dump the entire jump thread path into debugging dump.
	* tree-flow.h (register_jump_thread): Update prototype.

	* tree-ssa/ssa-dom-thread-3.c: Update due to changes in debug
	dump output.
