Anton Blanchard 9fbaea6f08 Rework CR file and add forwarding 
Handle the CR as a single field with per nibble enables. Forward any
writes in the same cycle.

If this proves to be an issue for timing, we may want to revisit
this in the future. For now, it keeps things simple.

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.
