+// This pass is used to promote memory references to be register references.  A
+// simple example of the transformation performed by this pass is:
+//
+//        FROM CODE                           TO CODE
+//   %X = alloca int, uint 1                 ret int 42
+//   store int 42, int *%X
+//   %Y = load int* %X
+//   ret int %Y
