	gcc            : ChangeLog.tree-ssa tree-dfa.c tree-ssa.c 

Log message:
	* tree-dfa.c (remove_phi_arg): Update PHI_ARG_CAPACITY.
	
	* tree-ssa.c (mark_def_sites): Do not build the dominator tree here.
	(rewrite_into_ssa): Do not depend on mark_def_sites to build the
	dominator tree.   Move computation of dominance frontiers out
	of main loop (even though it was only done once).  Free immediate
	dominator information as soon as we're done with it.
