// makeReturnCountMetric: A return count refers to the number of times
// a given CCT node is called by its parent context.  However, when
// hpcrun records return counts, there is no structure (e.g. procedure
// frames) in the CCT.  An an example, in the CCT fragment below, the
// return count [3] at 0xc means that 0xc returned to 0xbeef 3 times.
// Simlarly, 0xbeef returned to its caller 5 times.
//
//              |               |
//       ip: 0xbeef [5]         |
//       /      |      \        |
//   0xa [1]  0xb [2]  0xc [3]  |
//      |       |       |       |

// To be able to say procedure F is called by procedure G x times
// within this context, it is necessary to aggregate these counts at
