Denis Drakhnia ab620f7a2b e2k: Delete redundant unimplemented messages. 
DAM has not been yet implemented. We always generate
a jump to a fixing code. All these messages are redundant.

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.
