Arnaldo Carvalho de Melo b9fb930477 perf hist: Only allocate callchain_node if processing callchains 
The struct callchain_node size is 120 bytes, that are never used when
there are no callchains or '-g none' is specified, so conditionally
allocate it, reducing sizeof(struct hist_entry) from 210 bytes to only
96, greatly speeding the non-callchain processing.
