Andrey Semashev 18d5e470ba Initialize the dummy variable in x86 atomic_thread_fence(seq_cst). 
The initialization is not needed for the code, but it is needed to make
tools like valgrind happy. Otherwise, the tools would mark the instructions
as accessing uninitialized data.

Also, changed the dummy variable to a byte. This may allow for a more lax
alignment.
