	* c-typeck.c (build_function_call): Set fundecl = function again.
	* tree-ssa-alias.c (find_used_portions): Address taking causes the
	entire variable to be used.
	* tree-ssa-structalias.c (do_structure_copy): Fix handling of
	unknown size variables, and structure copies from addressof
	operations.  Simplify how we do *a = *b type structure copies.
	(init_base_vars): Add ANYTHING = &ANYTHING constraint the right
	way.  READONLY's address is not taken by default.
	INTEGER dereference should point to anything.
	(create_variable_info_for): It's okay for the first field to not start
	at 0.
