Implementation of the region-based ternary model described in:
 "A Memory Model for Static Analysis of C Programs"
  (Zhongxing Xu, Ted Kremenek, and Jian Zhang)
 http://lcs.ios.ac.cn/~xuzb/canalyze/memmodel.pdf   
The store models memory as a collection of "clusters", where regions
are partitioned into clusters via their base region.

For example, given:
  int a, b, c;
  struct coord { double x; double y; } verts[3];
then "verts[0].y" and "verts[1].x" both have "verts" as their base region.
Each of a, b, c, and verts will have their own clusters, so that we
know that writes to e.g. "verts[1].x".don't affect e.g. "a".

Within each cluster we store a map of bindings to values, where the
binding keys can be either concrete or symbolic.

Concrete bindings affect a specific range of bits relative to the start
of the base region of the cluster, whereas symbolic bindings affect
a specific subregion within the cluster.

Consider (from the symbolic-1.c testcase):

  char arr[1024];
  arr[2] = a;  (1)
  arr[3] = b;  (2)
    After (1) and (2), the cluster for "arr" has concrete bindings
    for bits 16-23 and for bits 24-31, with svalues "INIT_VAL(a)"
    and "INIT_VAL(b)" respectively:
    cluster: {bits 16-23: "INIT_VAL(a)",
              bits 24-31: "INIT_VAL(b)";
              flags: {}}
    Attempting to query unbound subregions e.g. arr[4] will
    return "UNINITIALIZED".
    "a" and "b" are each in their own clusters, with no explicit
    bindings, and thus implicitly have value INIT_VAL(a) and INIT_VAL(b).

  arr[3] = c;  (3)
    After (3), the concrete binding for bits 24-31 is replaced with the
    svalue "INIT_VAL(c)":
    cluster: {bits 16-23: "INIT_VAL(a)",  (from before)
              bits 24-31: "INIT_VAL(c)";  (updated)
              flags: {}}

  arr[i] = d;  (4)
    After (4), we lose the concrete bindings and replace them with a
    symbolic binding for "arr[i]", with svalue "INIT_VAL(d)".  We also
    mark the cluster as having been "symbolically touched": future
    attempts to query the values of subregions other than "arr[i]",
    such as "arr[3]" are "UNKNOWN", since we don't know if the write
    to arr[i] affected them.
    cluster: {symbolic_key(arr[i]): "INIT_VAL(d)";
              flags: {TOUCHED}}

  arr[j] = e;  (5)
    After (5), we lose the symbolic binding for "arr[i]" since we could
    have overwritten it, and add a symbolic binding for "arr[j]".
    cluster: {symbolic_key(arr[j]): "INIT_VAL(d)"; (different symbolic
              flags: {TOUCHED}}                     binding)

  arr[3] = f;  (6)
    After (6), we lose the symbolic binding for "arr[j]" since we could
    have overwritten it, and gain a concrete binding for bits 24-31
    again, this time with svalue "INIT_VAL(e)":
    cluster: {bits 24-31: "INIT_VAL(d)";
              flags: {TOUCHED}}
    The cluster is still flagged as touched, so that we know that
    accesses to other elements are "UNKNOWN" rather than
    "UNINITIALIZED".

Handling symbolic regions requires us to handle aliasing.

In the first example above, each of a, b, c and verts are non-symbolic
base regions and so their clusters are "concrete clusters", whereas given:
    struct coord *p, *q;
then "*p" and "*q" are symbolic base regions, and thus "*p" and "*q"
have "symbolic clusters".

In the above, "verts[i].x" will have a symbolic *binding* within a
concrete cluster for "verts", whereas "*p" is a symbolic *cluster*.

Writes to concrete clusters can't affect other concrete clusters,
but can affect symbolic clusters; e.g. after:
    verts[0].x = 42;
we bind 42 in the cluster for "verts", but the clusters for "b" and "c"
can't be affected.  Any symbolic clusters for *p and for *q can be
affected, *p and *q could alias verts.

Writes to a symbolic cluster can affect other clusters, both
concrete and symbolic; e.g. after:
    p->x = 17;
we bind 17 within the cluster for "*p".  The concrete clusters for a, b,
c, and verts could be affected, depending on whether *p aliases them.
Similarly, the symbolic cluster to *q could be affected.
