fed90b6d09 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.

e14d81deeb 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.

3e2dda63d0 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.

c9715624fa 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.

7dfda9e674 Smarter Reset(). Instead of deallocating all memory regions and reallocate the 
first region, just deallocate all but the last region in the list.

188b5224fd Added Reset() to free all allocated memory regions and reset state to be the same as right after ctor.

e81561909d Changed llvm_ostream et all to OStream. llvm_cerr, llvm_cout, llvm_null, are 
now cerr, cout, and NullStream resp.

72a780f577 Include llvm/Support/DataTypes.h to define intptr_t. 
This fixes the build on OpenBSD and potentially other systems.

9f617d64c5 Add a new llvm::Allocator abstraction, which will be used by a container 
I'm about to add.  This is similar to, but necessarily different than, the
STL allocator class.
