tree.h (DECL_BUILT_IN_NONANSI): Remove.

Browse Source 
* tree.h (DECL_BUILT_IN_NONANSI): Remove.
	* c-common.c (builtin_function_2): Don't set DECL_BUILT_IN_NONANSI.
	* c-decl.c (duplicate_decls): Use invariant DECL_BUILT_IN_NONANSI
	implies DECL_BUILT_IN to simplify logic.
	* print-tree.c (print_node): Don't dump DECL_BUILT_IN_NONANSI.
