An unsafe interface to use the dynamic memory manager directly, resembling
free. Manual memory management can be used in parallel to garbage collection, which can be quite handy, but manually managed blocks cannot be mixed with garbage collected objects (i.e. trying to
heap.free a GC object or casting a block to a managed object respectively would break since one has a GC header and the other does not).
# Static members
function heap.alloc(size: usize): usize
Allocates a chunk of memory of at least the specified size.
function heap.realloc(ptr: usize, size: usize): usize
Reallocates a chunk of memory to have at least the specified size.
function heap.free(ptr: usize): void
Frees a chunk of memory.
function heap.reset(): void
Dangerously resets the entire heap. Specific to the "stub" runtime.
