	* tree-ssa-pre.c (do_regular_insertion): Use the value number
	of edoubleprime for the value number of the expr.
	* tree-ssa-sccvn.c (vn_reference_lookup_pieces): Do not start
	walking if we found an expression, even if its value number
	is NULL.

	decl.
	(find_what_var_points_to): Always pass a decl to set_uids_in_ptset.
