Description:
There are unnecessary calling of __atomic_thread_fence() as a workaround
of gcc bug#77673. This bug was fixed both for GCC 5.5 and GCC 6.3 so
the original workaround is no more required for these GCC versions and
more recent.

How to repeat:
Inspect source code in the file storage/innobase/mach/mach0data.cc
