A simple mark and sweep garbage collector.
This is a very simple (but not too inefficient) toy garbage collector, based on the mark and sweep algorithm. It supports three types: Objects, Arrays and 32-bit Integers. This GC supports inheritance.
The program must be single-threaded.
Any value in the stack is treated as a GC root, even if it's not a pointer. The GC is only run on allocation. If there's no lack of memory, then the GC will never run.
The "gc_heap" are pages of heap memory that are used to store the objects, arrays and array contents.
