testsuite: Replace many dg-require-thread-fence with dg-require-atomic-cmpxchg-word
These tests actually use a form of atomic compare and exchange
operation, not just atomic loading and storing. Some targets (not
supported by e.g. libatomic) have atomic loading and storing, but not
compare and exchange, yielding linker errors for missing library
functions.
This change is just for existing uses of
dg-require-thread-fence. It does not fix any other tests
that should also be gated on dg-require-atomic-cmpxchg-word.
* testsuite/29_atomics/atomic/compare_exchange_padding.cc,
testsuite/29_atomics/atomic_flag/clear/1.cc,
testsuite/29_atomics/atomic_flag/cons/value_init.cc,
testsuite/29_atomics/atomic_flag/test_and_set/explicit.cc,
testsuite/29_atomics/atomic_flag/test_and_set/implicit.cc,
testsuite/29_atomics/atomic_ref/compare_exchange_padding.cc,
testsuite/29_atomics/atomic_ref/generic.cc,
testsuite/29_atomics/atomic_ref/integral.cc,
testsuite/29_atomics/atomic_ref/pointer.cc: Replace
dg-require-thread-fence with dg-require-atomic-cmpxchg-word.
