    libstdc++: Remove redundant -std=gnu++17 option from concurrency tests
    
    GCC defaults to -std=gnu++17 now anyway, and using it explicitly in the
    dg-options directive prevents running these tests with different modes
    such as -std=c++17 or -std=gnu++20.
    
    libstdc++-v3/ChangeLog:
    
            * testsuite/29_atomics/atomic/69769.cc: Remove -std=gnu++17 from
            dg-options.
            * testsuite/29_atomics/atomic/is_always_lock_free.cc:
            * testsuite/29_atomics/atomic/requirements/typedefs.cc:
            * testsuite/29_atomics/atomic_integral/is_always_lock_free.cc:
            * testsuite/29_atomics/atomic_integral/requirements/typedefs.cc:
            * testsuite/30_threads/lock_guard/cons/deduction.cc: Likewise.
            * testsuite/30_threads/scoped_lock/cons/1.cc: Likewise.
            * testsuite/30_threads/scoped_lock/cons/deduction.cc: Likewise.
            * testsuite/30_threads/scoped_lock/requirements/explicit_instantiation.cc:
            Likewise.
            * testsuite/30_threads/scoped_lock/requirements/typedefs.cc:
            Likewise.
            * testsuite/30_threads/shared_lock/70766.cc: Likewise.
            * testsuite/30_threads/shared_mutex/cons/1.cc: Likewise.
            * testsuite/30_threads/shared_mutex/cons/assign_neg.cc:
            Likewise.
            * testsuite/30_threads/shared_mutex/cons/copy_neg.cc: Likewise.
            * testsuite/30_threads/shared_mutex/requirements/standard_layout.cc:
            Likewise.
            * testsuite/30_threads/shared_mutex/try_lock/1.cc: Likewise.
            * testsuite/30_threads/shared_mutex/try_lock/2.cc: Likewise.
            * testsuite/30_threads/shared_mutex/unlock/1.cc: Likewise.
            * testsuite/30_threads/unique_lock/cons/deduction.cc: Likewise.
    
    (cherry picked from commit 9cd88c022fcad783997cd4111b2e6c3700c4b15b)
