This patch changes some of the dejagnu options to better restrict

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.
