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.
