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,
...
for handling bookkeeping for deleted objects, as well as the alist class
template, for keeping lists of objects allocated from Recyclers, and some
related utilities.

Fix a pointer-arithmetic bug that caused 64-bit host pointer values to
...
be truncated to 32 bits. This fixes the recent Benchmarks/McCat/09-vor
regression on x86-64, among other things.

Bug fix in BumpPtrAllocator: don't assume that all objects have the same alignment. "Bump" of the pointer for the next allocated object to be of the specified alignment.

Smarter Reset(). Instead of deallocating all memory regions and reallocate the
...
first region, just deallocate all but the last region in the list.
