perf c2c report: Display Total records column in offset view

Adding "Total records" column into cacheline pareto table, between
cycles and cpu info.

  $ perf c2c report
  ...

  ---    ---------- cycles ----------    Total       cpu
         rmt hitm  lcl hitm      load  records       cnt
  ...    ........  ........  ........  .......  ........

                0       112        71       34         4
                0         0         0       18         1
                0         0         0        2         1
                0       132         0        3         3

  ...

It's useful to see how many recorded samples represent each offset.
