perf c2c: Add local variables for output metrics
This patch adds several local variables:
"cl_output": pointer for outputting single cache line metrics;
"output_str": pointer for outputting cache line metrics;
"sort_str": pointer to the sorting metrics.
This can improve readability for the code and it's more flexible when
later extend to different strings for the output metrics.
