Modified files:
	gcc            : Makefile.in ChangeLog.tree-ssa ssa.c tree-ssa.c 

Log message:
	* Makefile.in (ssa.o): Depends on $(TREE_H) and tree-flow.h
	* ssa.c: Include tree.h and tree-flow.h.
	(compute_dominance_frontiers_1): Use the sparse bitmap
	of dominator children from the basic block's annotation
	if it's available.  Otherwise build the sparse bitmap
	using the result of get_dominated_by.
	* tree-ssa.c (rewrite_into_ssa): Reorder things slightly so
	that we can use the cached dominator children computed
	by mark_def_sites in compute_dominance_frontiers.
