Various additions and changes to compiler backend for IFs and calls
...
Branching now exists in a general way (work for tests requiring
multiple branch instructions still needed) that works for both storing
test results and taking branches in code.
De-duplicated arguments to calls now load correctly.

Make assembly program representation smarter
...
Storing assembly instructions in a list felt nice since that lets me
just fire and forget, but if we want to properly optimize short
branches (i.e. branches that do not require a full JMP) we'll need to
be able to rewrite assembly after linking, and I feel that's best done
by making assembly instructions hold a NEXT rather than poking at a
list clumsily.
The first linking pass was also moved out to a separate function since
we may want to run the first pass twice, first after the initial
assembling and second after expanding optimistic short branches (those
that turned out to be longer branches than 127/128 bytes) into a long
branch snippet (branch with inverted condition skipping over a JMP).
