Anton Blanchard 9cbdecb561 Fix CR forwarding 
We weren't actually forwarding writes in the same cycle. Not a
problem right now, but noticed when testing the pipelining series.

Anton Blanchard 0254e40685 Fix issues with CR rework 
It simulated fine, but didn't synthesize. Fix some obvious issues
to get us going again.

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.
