Hi Everyone,

I wanted to let everyone know that the format of the statistics file
has changed with a recent commit that I made.  Up until today, M5 had
an option to print statistics in a simplescalar compatible output
format.  The default was usually to use this compatibility mode, but
due to an initialization bug, sometimes this wouldn't happen.  There
were even examples of committed tests where some of the tests were in
one mode and some were in another.  The combination of this bug, the
fact that the compatibility mode isn't that important, and the fact
that it just made the code more complicated, I've removed the
compatibility mode.  All statistics outputs should be consistent now.

As a side benefit, I believe that people will find that the new text
format is much easier to parse now.  One notable change was that
"<err: div-0>" and "no value" are both now "no_value".  This makes the
new format easily parsed using white space to separate into three
colums: stat name, value, and an option comment/description.

  Nate
