	gcc            : ChangeLog.tree-ssa timevar.def tree-dump.c 
	                 tree-flow.h tree-optimize.c tree-ssa-dom.c 
	                 tree.h 

Log message:
	* timevar.def (TV_TREE_SSA_THREAD_JUMPS): Kill.
	* tree-dump.c (dump_files): Kill .thread dump.
	* tree.h (TDI_thread_jumps): Kill.
	* tree-flow.h (tree_ssa_dominator_thread_jumps): Kill prototype.
	* tree-optimize.c (optimize_function_tree): Kill call to
	tree_ssa_dominator_thread_jumps.
	* tree-ssa-dom.c (thread_through_phis): Kill.  We no longer need
	to restrict threading through PHIs.
	(tree_ssa_dominator_thread_jumps): Kill.
	(tree_ssa_domiantor_optimize_1): Fold back into
	tree_ssa_dominator_optimize.
	(tree_ssa_dominator_optimize): Mark back edges in the flow graph.
	Kill code which conditionalized the walk_tree callbacks based
	on thread_through_phis.  When threading jumps, reorganize code
	so that we can take the affected variables out of SSA form.
	Mark new variables created by out-of-ssa code as needing to be
	rewritten.
	(thread_across_edge): Always allow threading through phis.
	(thread_jumps_walk_stmts): Kill.
