PR c++/19407
* cp/cp-tree.h (ATTR_IS_DEPENDENT): New macro.
(MAYBE_TAGGED_TYPE_P): Remove.
* cp/pt.c (apply_late_template_attributes): Check ATTR_IS_DEPENDENT
instead of calling is_late_template_attribute again.
(tsubst_decl) [TYPE_DECL]: Just check if the name is the tag.
(tsubst): A typedef is a TYPE_NAME != TYPE_MAIN_DECL.
Don't crash on typedefs from non-template classes.
* cp/decl2.c (grokfield): Don't sorry about attrs on template parms.
(is_late_template_attribute): All attributes applied to template
parms or typename types are dependent. Static, take decl.
(splice_template_attributes): Pass decl through.
(save_template_attributes): Likewise.
* attribs.c (lookup_attribute_spec): Split out...
(decl_attributes): From here.
* tree.h: Declare it.
