I suppose this could/should wait till GCC 17.
Bootstrapped/regtested on x86_64-pc-linux-gnu, ok for trunk?

During Reflection review it came up that is_std_substitution
handles NAMESPACE_DECLs accidentally: it wants either a class or a
class template, but is looking at the type of any decl.
gcc/cp/ChangeLog:
* mangle.cc (is_std_substitution): Instead of any _DECL, only
accept TYPE_DECL and DECL_CLASS_TEMPLATE_P. Use NULL_TREE
instead of NULL.
