c-parse.in (SAVE_WARN_FLAGS): Create an INTEGER_CST.

Browse Source 
* c-parse.in (SAVE_WARN_FLAGS): Create an INTEGER_CST.
	(RESTORE_WARN_FLAGS): Unpack it.
	Change semantic type of extension to ttype.
	* c-common.c (split_specs_attrs): Expect an INTEGER_CST.
	* c-parse.y, c-parse.c, objc/objc-parse.y,
	objc/objc-parse.c: Regenerate.
