...
This replaces r151834 with a simpler fix.

If BumpPtrAllocator is requested to allocate a size that exceeds the slab size,
...
increase the slab size.

Fix unit test on FreeBSD. We need to make sure there is enough space to save the pointer even if the memory returned from malloc was already aligned.

Added a test and fixed a bug in BumpPtrAllocator relating to large alignment

values. Hopefully this fixes PR4622.

Reverting r76825 and r76828, since they caused clang runtime errors and some build failure involving memset.

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.
