c++: crash with anon VAR_DECL [PR116676]

r12-3495 added maybe_warn_about_constant_value which will crash if
it gets a nameless VAR_DECL, which is what happens in this PR.

We created this VAR_DECL in cp_parser_decomposition_declaration.

PR c++/116676

gcc/cp/ChangeLog:

* constexpr.cc (maybe_warn_about_constant_value): Check DECL_NAME.

gcc/testsuite/ChangeLog:

* g++.dg/cpp1z/constexpr-116676.C: New test.
