Denis Drakhnia 52e67df3a1 e2k: Reorg usage of registers. 
Till then we had separate stage to write results of
an operations to registers. Now operations will write
result immediately to a destination register. Registers
will be saved to a temporary location if following
operations in a bundle must read them.

The change elliminates additional branches for
conditional operations in the write stage and reduces
data movements.

Denis Drakhnia b0a1af39c6 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.
