Add value allocator (typically called register allocator)
...
It's unfinished and doesn't optimize space used by temporary
variables. Every temporary gets its own memory slot right now.

Add compiler optimization to get rid of IR-FETCHVARs when unneeded
...
It replaces the IR-FETCHVAR's result with the variable being
fetched. This only works when the only use is in an operation that
does not require a separate fetch be performed, such as those
implemented as CPU instructions.

Add compiler middle stage
...
The compiler middle stage takes high level nodes and produces code in
an intermediate representation more closely resembling assembly code.
Optimizations and the tools for making those are also included. It's
significantly easier to optimize IR than syntax trees or assembly.
Several things need cleaning up, in particular there are things in
jigs.lisp that really should be documented tools, not
jigs (specifically the compilation setup and finalization).

It ingests tokens via a "token stream", and feeds out a node

occasional Lisp macros for convenience.
