changes.html to mention Pavel's contribution

[Jan Hubicka]

Hi,
I think we should mention Pavel's .da format changes because they are quite
significant and can confuse people by losing backward compatibility for gcov
output (I already received first questions about that).

The entry is bit more verbose than I would like, but my english is not
good enought to say it in more compact way.

    <ul>
      <li>A new scheme for accurately describing processor pipelines has been
          added for GCC 3.2 (aka the DFA scheduler).</li>
+     <li>Pavel Nejedly, Charles University Prague, has contributed new arc
+ 	profiler file format.  The new format is robust, diagnoze common
+ 	mistakes resulting in nonsential profiles and allows overall statistics
+ 	to be generated.  This helps optimizers to identify hot spots of a
+ 	program globally replacing the old intraprocedural scheme resulting in
+ 	smaller code generated. Note that <tt>gcov</tt> tool from the older GCC
+ 	versions will not be able to parse the profiles generated by the new GCC
+ 	and vice versa.</li>
    </ul>
