High performance VM #13

The reference implementation of the VM is not optimized for speed and has loads of paranoid checks. Once things stabilize I will attempt an optimized version in 6502 assembly.

I have started down this road: 1) using a jump table for VM instruction dispatch. 2) moving common registers and eval stack to zero page. 3) hand-optimized assembler to shave a few instructions This work is in v0.78.
