* altos/lisp: Change lisp objects to use ao_poly everywhere. Add constKeith Packard2017-02-20
This makes all lisp objects use 16-bit ints for references so we can hold more stuff in small amounts of memory. Also adds a separate constant pool of lisp objects for builtins, initial atoms and constant lisp code. Now builds (and runs!) on the nucleo-32 boards. Signed-off-by: Keith Packard <keithp@keithp.com>
