+
+Abstract:
+
+    Reduce the number of bits used to encode constants, by using signed bounds.
+    Example: suppose x is a bit-vector of size 8, and we have
+    signed bounds for x such that:
+        -2 <= x <= 2
+    Then, x can be replaced by  ((sign-extend 5) k)
+    where k is a fresh bit-vector constant of size 3.
