This patch changes some of the dejagnu options to better restrict
where the test cases run so that they will no longer cause failures on
power7 machines.

Based on a subsequent patch I also updated the code formatting (indentation,
etc.) for the code from the original patch (r235577) in both the test cases
and in rs6000-c.c.
