[PATCH 3/5] perf,tools: save misc sample read value in struct perf_sample

[kan . liang]

From: Kan Liang <kan.li...@intel.com>

Save group read results from cycles/ref-cycles/TSC/ASTATE/MSTATE in
struct perf_sample. The following sample process function can easily
use them to caculate freq/CPU%/CORE_BUSY% and add them in hists.
