Subject: [PATCH v6 3/3] tools/testing/fpu: Add a 'count' column.

Show the total number of each combination of event-RFBM-XINUSE. Users can
identify which data is noise and focus more on useful data.

The sample of the output is as follows:
EVENTs         RFBM     XINUSE   CNT     min   max   avg   avg(97%)
---...-------  -------  -------  ------  ----  ----  ----  --------
x86..._xrstor  0x20ee7  0x0      1       xx    xx    xx    xx
x86..._xrstor  0x20ee7  0x2a2    997860  xx    xxx   xx    xx
