Oh, wow, I forgot that we hadn't implemented register spilling in the 
new vertex shader backend.  Yeah, that would be nice.

I also haven't implemented spilling in the FS on Ivybridge...need to 
finish that.  Before I can do that, I need to properly reserve g111-g127 
for use as fake MRFs.  (I had hoped to have a real solution, but never 
managed.)  But it's already broken and should be fixed, so...it 
shouldn't really affect the decision here.
