Benjamin Herrenschmidt 3e6f656a90 Add MCRF instruction
Hopefully it's not too timing catastrophic. The variable newcrf will
be handy for the other CR ops when we implement them I suspect.

Anton Blanchard 5e140298a5 Rework decode2
The decode2 stage was spaghetti code and needed cleaning up.
Create a series of functions to pull fields from a ppc instruction
and also a series of helpers to extract values for the execution
units.

As suggested by Paul, we should pass all signals to the execution
units and only set the valid signal conditionally, which should
use less resources.
