gdbsupport: allow passing nullptr to checked_static_cast
Both static_cast and dynamic_cast handle nullptr (they return nullptr),
so I think checked_static_cast should too. This will allow doing a null
check after a checked_static_cast:
cooked_index_vector *table
= (gdb::checked_static_cast<cooked_index_vector *>
(per_bfd->index_table.get ()));
if (table != nullptr)
return;
