Fix assertion in gc_object_left_behind() to work in Gen-0 collection.
Add (weak-box?) and (make-weak-box) primitives. (unbox) now works for both.
Add option to just simplify the input (stops before reduce-function).
Default to writing .rla without indentation, comments, or newlines.
Add support for (fix=), (list), (and), (or), (cond), (when), and (unless).
Fix a mapper bug which could assign the same frame var to separate variables.
Update make-struct primitive for new structure type layout.
Change primitives to use #% as prefix instead of just %.
Add primitive operations for comparing byte-strings.
Pairs, boxes, and strings are hashed by values; vectors and structures
are "hashed" by reference. Takes into account the possibility of cycles.
This is a prelude to implementing hash-tables.
Created one module one per pass, plus utilities functions, primitives, and output.
Changed extension to ".scm" for compatibility with hg syntax highlighting backend.
