vm optimization

now it's time to reduce code. it's not very fast anyway, so no reason
to start spilling bytes. but this is for later. got some stuff to get
ready now.

i'm happy with how it's looking though. some minor things need fixing,
probably the most important one being return stack alignation.

something to focus on is to limit the number of macros. i probably
only need conditionals, the rest can be written in forth even. macros
are only necessary for marking jumps.
