c++: find A pack from B in <typename...A,Class<A>...B> [PR118265]
For non-type parameter packs when unifying the arguments in
unify_pack_expansion it iterates over the associated packs of a param so
that when it recursively unifies the param with the arguments it knows
which targs have been populated with parameter pack arguments that it can
then collect up. This change adds a tree walk so that in the example above
it reaches ...A and adds it to the associated packs for ...B and therefore
knows it will have been set in targs in unify_pack_expansion and processes
it as per other pack arguments.
