Parameterize the BumpPtrAllocator over a slab allocator. It defaults to using
...
malloc, so there should be no functional changes to other code.
These changes are necessary since I have plans to use this allocator in the JIT
memory manager, and it needs a special allocator.
I also added some tests which helped me pinpoint some bugs.
