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.

Fold the useful features of alist and alist_node into ilist, and
...
a new ilist_node class, and remove them. Unlike alist_node,
ilist_node doesn't attempt to manage storage itself, so it avoids
the associated problems, including being opaque in gdb.
Adjust the Recycler class so that it doesn't depend on alist_node.
Also, change it to use explicit Size and Align parameters, allowing
it to work when the largest-sized node doesn't have the greatest
alignment requirement.
Change MachineInstr's MachineMemOperand list from a pool-backed
alist to a std::list for now.

Add some basic Pool-allocation infrastructure. This adds a Recycler class,

template, for keeping lists of objects allocated from Recyclers, and some
