    libstdc++: bitset subscript check when _GLIBCXX_ASSERTIONS [PR118341]

    Changes in v3:
     - Delete redundant "dg" annotations.

    Changes in v2:
     - Rejigger testing.
     - Add tests for regular bitset<>::op[].

    Perform __glibcxx_assert bounds check on indices to bitset<>::op[]
    for const and non-const overloads.

    Also, add previously neglected regular tests for bitset<>::op[].
