[PATCH v1 1/8] perf mem: Add structure field c2c_stats::tot_llchit

[Leo Yan <leo.yan@linaro.org>]

Add new field c2c_stats::tot_llchit to count total number for LLC hit:

  c2c_stats::tot_llchit = c2c_stats::lcl_hitm + c2c_stats::ld_llchit

This is the preparation for additional sorting with total LLC hit, and
will be used in perf c2c report in following patches.
