perf hists: Separate overhead and baseline columns

Browse Source 
Currently the overhead and baseline columns are handled within single
function and the distinction is made by 'baseline hists' pointer passed
by 'struct perf_hpp::ptr'.

Since hists pointer is now part of each hist_entry, it's possible to
locate paired hists pointer directly from the passed struct hist_entry
pointer.

Also separating those 2 columns makes the code more obvious.
