* decl.c (maybe_push_to_top_level): Always clear
	current_template_parms and processing_template_decl.
	(pushtag): Remove check of current_class_type and some comments,
	since maybe_push_to_top_level no longer creates confusion.

says that we are looking at a primary template

just drop the `in class scope' and then not check
GLOBALIZE either since on this code:

maybe_push_to_top_level which doesn't clear
processing_template_decl, so we would then
incorrectly call push_template_decl. */
