Masami Hiramatsu (Google) ccf47f5cc4 tracing: Add nohitcount option for suppressing display of raw hitcount 
Add 'nohitcount' ('NOHC' for short) option for suppressing display of
the raw hitcount column in the histogram.
Note that you must specify at least one value except raw 'hitcount'
when you specify this nohitcount option.
