Adding 5 hitm related dimension key wrappers.

First 3 are to be displayed in the main cachelines
overall output:

  tot_hitm, lcl_hitm, rmt_hitm

The latter 2 are to be displayed within single
cacheline output:

  cl_rmt_hitm, cl_lcl_hitm

They all display bare numbers of remote/local/total
HITMs for cacheline or its related offsets.
