Arnaldo Carvalho de Melo 41477acf09 perf hists: Save the callchain_size in struct hist_entry 
So that we can figure out the real size of the struct and also be able
to tell if callchains may be present in this histogram entry.

Since we can't always guarantee that from hist_entry->hists we can use
hists_to_evsel, to then look at evsel->attr.sample_type for
PERF_SAMPLE_CALLCHAIN, like with the 'perf c2c' tool, that uses plain
'struct hists' instances, we need another way of deciding if a specific
hist_entry instance has callchains associated with it, i.e. if its
hist_entry->callchain[0] has space allocated for.
