This ensures coverage for the inplace_vector<T, 0> specialization. Also extends element access tests to cover front() and back() methods, and const and mutable overloads for all accesses. PR libstdc++/119137 libstdc++-v3/ChangeLog: * testsuite/23_containers/inplace_vector/access/elem.cc: Cover front and back methods and const calls. * testsuite/23_containers/inplace_vector/access/elem_neg.cc: Likewise. * testsuite/23_containers/inplace_vector/modifiers/erase_neg.cc: New test. * testsuite/23_containers/inplace_vector/modifiers/single_insert_neg.cc: New test.
