Slisp: Simple Lisp compiler (Linux/amd64)

Slisp is a compiler that transforms Lisp programs into standalone assembly code for Linux/AMD64 systems, enabling non-interactive execution of compiled binaries rather than traditional interactive REPL-based Lisp usage. The compiler supports a comprehensive feature set including functions, lambdas with closures, file I/O, mathematical operations, and a stop-and-copy garbage collector using Cheney's algorithm. Example programs demonstrate its capabilities through implementations like a brainfuck interpreter, Game of Life, N-Queens solver, and various standard algorithms.
