PR c++/83205
* decl.c (cp_finish_decomp): Handle the case when tsize is not
error_mark_node, but doesn't fit into uhwi.  Split up count != eltscnt
and !tree_fits_uhwi_p (tsize) error_at calls into error_n and inform_n
to handle plural forms properly.

* g++.dg/cpp1z/decomp3.C: Adjust for structured binding count
mismatch diagnostics split into error and warning with plural
forms.
* g++.dg/cpp1z/decomp10.C: Likewise.
* g++.dg/cpp1z/decomp32.C: New test.
