c++: Fix constexpr vs. omitted aggregate init.

Value-initialization is importantly different from {}-initialization for
this testcase, where the former calls the deleted S constructor and the
latter initializes S happily.

PR c++/90951
* constexpr.c (cxx_eval_array_reference): {}-initialize missing
elements instead of value-initializing them.
