Modified files:
	gcc            : ChangeLog.tree-ssa Makefile.in timevar.def 
	                 tree-dfa.c tree-ssa.c tree-flow.h 
Added files:
	gcc            : tree-ssa-dom.c 

Log message:
	* Makefile.in (OBJS): Add tree-ssa-dom.o
	(tree-ssa-dom.o): Add dependencies.
	(ssa.o, cfghooks.o): Use $(TREE_FLOW_H), not tree-flow.h.
	* timevar.def: Add new timevar for dominator optimizer.  Reorder
	slightly.
	* tree-dfa.c (add_stmt_operand): Do not consider references to
	static storage as volatile operands.
	(add_referenced_var): Static storage items reference global memory.
	* tree-ssa.c: Simplify by moving everything specific to the
	dominator optimizer into tree-ssa-dom.c.  Call into the dominator
	optimizer after rewriting all the basic blocks.
	* tree-ssa-dom.c: New file.  Mostly extracted from tree-ssa.c
	* tree-flow.h (tree_ssa_dominator_optimize): Prototype.
	(dump_dominator_optimization_stats): Likewise.
	(debug_dominator_optimization_stats): Likewise.
