SpecIterator -> TemplateArgumentList

Hi,

r109870 introduced the SpecIterator class with spec_begin()/spec_end() methods on the FunctionTemplateDecl class, moving getSpecializations() to protected access.

By dereferencing the iterator I can get the equivalent of FunctionTemplateSpecializationInfo::Function. But how does one reach the TemplateArgumentList of the specialization? I assume there is an orthogonal mechanism which I am missing.

Thanks,

FunctionDecl::getTemplateSpecializationArgs().
