If you want the whole structured bindings to be mangled normally as if the
pack isn't a pack and the individual vars of the structured binding pack
mangled as multiple occurrences of the named entities, the following
patch does that.

* decl.cc (cp_finish_decomp): Don't sorry on tuple static
structured bindings with a pack, instead temporarily reset
DECL_NAME of the individual vars in the pack to the name
of the pack for cp_finish_decl time and force mangling.
* g++.dg/cpp26/decomp19.C: Don't expect sorry on tuple static
structured bindings with a pack.
* g++.dg/cpp26/decomp26.C: New test.
