Indicate both start and end of pass RSS in time-passes output

Browse source 
Previously, only the end of pass RSS was indicated. This could easily
lead one to believe that the change in RSS from one pass to the next was
attributable to the second pass, when in fact it occurred between the
end of the first pass and the start of the second.

Also, improve alignment of columns.
