d940baccc9 perf c2c report: Display total HITMs on default
Currently we display the cacheline list sorted on remote HITMs by
default.

The problem is that they might not be always counted and 'perf c2c
report' displays an empty output. Thus it's more convenient to display
and sort the cacheline list based on the total of HITMs and have the
best change to see data in the default report run.

af09b2d35e perf c2c report: Add --show-all option
Normally we limit the main list to contain only entries with HITM %
value > 0.0005, but it might be useful to display all captured entries.
Adding --show-all option for that.

18f278d2dd perf c2c report: Add --no-source option
Add a possibility to disable source line column with new --no-source
option. It source line data could take lot of time to retrieve, so it
could be a performance burden for big data.
