    perf tools: Allow sorting by symbol size · 7768f8da
    Charles Baylis authored
    Add new sort key 'symbol_size' to allow user to sort by symbol size, or
    (more usefully) display the symbol size using --fields=...,symbol_size.
    
    Committer note:
    
    Testing it together with the recently added -q, to remove the headers,
    and using the '+' sign with -s, to add the symbol_size sort order to
    the default, which is '-s/--sort comm,dso,symbol':
