As agreed on https://github.com/itanium-cxx-abi/cxx-abi/issues/109 these placeholders should be mangled as a `template-prefix` production. ``` <template-prefix> ::= <template unqualified-name> # global template ::= <prefix> <template unqualified-name> # nested template ::= <template-param> # template template parameter ::= <substitution> ``` Previous to this patch, the template template parameter case was not handled, and template template parameters were incorrectly being handled as unqualified-names. Before #95202, DeducedTemplateType was not canonicalized correctly, so that template template parameter declarations were retained uncanonicalized. After #95202, they are correctly canonicalized, but this now leads to these TTPs being anonymous entities, where the mangling implementation correctly doesn't expect an anonymous declaration of this kind, leading to a crash. Fixes #106182.
