Subject: [PATCH 19/52] perf c2c report: Add llc and remote loads related dimension keys

From: Jiri Olsa <jolsa@...nel.org>

Add 2 LLC load related dimension key wrappers.

They are to be displayed in the main cachelines overall output:

  ld_lclhit, ld_rmthit

They display bare numbers of LLC and remote loads for cacheline.
