c++: Fix ICE with structured binding initialized to incomplete array
[PR97878]
We ICE on the following testcase, for incomplete array a on auto [b] { a };
without
giving any kind of diagnostics, with auto [c] = a; during error-recovery.
The problem is that we get too far through check_initializer and e.g.
store_init_value -> constexpr stuff can't deal with incomplete array types.
As the type of the structured binding artificial variable is always
deduced,
I think it is easiest to diagnose this early, even if they have array types
we'll need their deduced type to be complete rather than just its element
type.
