libstdc++: Add dg-require-thread-fence in several tests
Some targets like arm-eabi with newlib and default settings rely on
__sync_synchronize() to ensure synchronization. Newlib does not
implement it by default, to make users aware they have to take special
care.
This makes a few tests fail to link.
This patch requires the missing thread-fence effective target in the
tests that need it, making them UNSUPPORTED instead of FAIL and
UNRESOLVED.
