Denis Drakhnia 17be44b21b e2k: Use one large array for registers. 
Previously was used two separate arrays for low and
high halves of a register. Now we can pass direct
pointer to a register into helpers instead of copying
the halves into a temporary buffer and pass pointer to
that buffer.

Denis Drakhnia e404c06a2d e2k: Fix syscall restart. 
We cannot just change the IP address in E2K to restart
the instruction because the same register can be read
and written in the same instruction (and many more
situations), but we can create a fake syscall instruction
and restart it.
