within the instantiation of that same specialization. This could previously happen for eagerly-instantiated function templates, variable templates, exception specifications, default arguments, and a handful of other cases. We still have an issue here for default template arguments that recursively make use of themselves and likewise for substitution into the type of a non-type template parameter, but in those cases we're producing a different entity each time, so they should instead be caught by the instantiation depth limit. However, currently we will typically run out of stack before we reach it. :( llvm-svn: 280190
