With simple template names the template arguments aren't embedded in the DW_AT_name attribute of the type. The code in FindDefinitionTypeForDWARFDeclContext was comparing the synthesized template arguments on the leaf (most deeply nested) DIE, but was not sufficient, as the difference get be at any level above that (Foo<T>::Bar vs. Foo<U>::Bar). This patch makes sure we compare the entire context. As a drive-by I also remove the completely unnecessary ConstStringification of the GetDIEClassTemplateParams result.
