The only error that the vertex shader precompile could generate is
when register allocation fails. Since i965 can spill registers, this
should never happen. It's also not something that can cause a link
error.
This change will take those shaders from failing to link to segfaulting.
Yeah, it would be nice to finish register allocation.
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.
