[Allocator] Lift the slab size and size threshold into template
...
parameters rather than runtime parameters.
There is only one user of these parameters and they are compile time for
that user. Making these compile time seems to better reflect their
intended usage as well.

Fix layering StringRef copy using BumpPtrAllocator.
...

BumpPtrAllocator: Make sure threshold cannot be initialized with a value smaller than the slab size.

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.
