That's a surprising amount!
As is, the patch doesn't actually enable 16-wide math on G45 as claimed,
since we don't do 16-wide on G45 at all. But it does set it up to work
in the future, if/when we do enable 16-wide. So I think it's okay as
is, but if people would prefer to see a s/g45/gen5/g, I'm okay with that
If you'd like to put a R-b on it, mention the 2% performance
improvement, and push it, that would be great.
