builtins.c (get_pointer_alignment, [...]): Use POINTER_TYPE_P instead TREE_CODE… 

builtins.c (get_pointer_alignment, [...]): Use POINTER_TYPE_P instead TREE_CODE checking against POINTER_TYPE.

	* builtins.c (get_pointer_alignment, gimplify_va_arg_expr,
	expand_builtin_printf, expand_builtin_fprintf,
	expand_builtin_sprintf): Use POINTER_TYPE_P instead TREE_CODE
	checking against POINTER_TYPE.
	(validate_arglist): Handle POINTER_TYPE code by checking
	POINTER_TYPE_P.
	* g++.dg/tree-ssa/empty-1.C: New test.
