with -m32 (i.e. for i386). Previously if this was attempt allocations
in the program being executed by KLEE would hit an assertion because
malloc() would return an address that doesn't fit in a 32-bit pointer.
The interface of MemoryManager has been changed so that it is necessary
to specify the pointer size on creation. The implementation has been
changed to use a MASSIVE HACK when the pointer width is less than
64-bits.

Addresses the issue raised by Bowen Zhou at http://keeda.stanford.edu/pipermail/klee-dev/2012-November/000972.html.
Fixed test case that depended on the old behavior.

leak in KLEE.
From Gang Hu: "The memory leak is caused by two reasons. First, the
MemoryObject objects are not freed, until the MemoryManager is
destroyed. Second, when KLEE allocates a non-fixed MemoryObject
object, KLEE also allocates a block of memory which is the same as the
object's size. This block of memory is never freed. So, this patch
generally does reference counting on the MemoryObject objects, and
frees them as soon as the reference count drops to zero."
Many thanks to Paul Marinescu as well, who tested this patch
thoroughly on the Coreutils benchmarks. On 1h runs, the memory
consumption typically goes down by 1-5%, but some applications which
see more significant gains.

to klee_error() to make sure the check is done even when assertions
are disabled. This makes the AsmAddresses test pass with assertions
disabled.

- Lots more tweaks, documentation, and web page content is needed,
but this should compile & work on OS X & Linux.
