- change the FormatFlags into more general StatFlags

-  make init and print StatFlags
-  default_mode -> DefaultMode
-  the display mode is no longer needed as part of the stat
pass it into the display functions so the mode can be determined
from dump to dump
-  get rid of old simplescalar bug and make the distribution min_val
work correctly
-  get rid of the DisplayMode parameter to distribution updates since
it is no longer needed
