Andi Kleen f948339290 perf stat: Add support for metrics in interval mode 
Now that we can modify the metrics printout functions easily, it's
straight forward to support metric printing for interval mode.  All that
is needed is to print the time stamp on every new line.  Pass the prefix
into the context and print it out.

v2: Move wrong hunk to here.

Committer note:

Before:

  [root@jouet ~]# perf stat -I 1000 -e instructions,cycles sleep 1
  #           time    counts unit events
       1.000168216   538,913      instructions
       1.000168216   748,765      cycles
       1.000660048   153,741      instructions
       1.000660048   214,066      cycles

After:

  # perf stat -I 1000 -e instructions,cycles sleep 1
  #           time    counts unit events
       1.000215928   519,620      instructions              #    0.69  insn per cycle
       1.000215928   752,003      cycles
       1.000946033   148,502      instructions              #    0.33  insn per cycle
       1.000946033   160,104      cycles
