e2k: Add a fake atomic execution.
...
QEMU has cpu_exec_step_atomic function to run
one instruction in an exclusive mode but we need
to execute multiple instructions in that mode.
I don't want to modify the function.
The solution provides a correct execution of
atomic operations like on real CPU but needs
more testing to prove that it works correctly
in all cases.
