[power7-meissner] Change constraints setup; Add debug switches; Make power7 scheduling like power5


This patch changes how the register constraints are setup, to use an array to
hold the constraints for each of the register constraints that can vary at
runtime ("d", "f", etc.).

It also adds some new debug switches to try an isolate some performance issues,
and makes the power5 schedule like a power7.
