[Mesa-dev] [RFC] some glsl->tgsi optimisations

[Samuel Pitoiset]

Hi Dave,

Can you rebase your series on top of master because it doesn't apply.

I'm fine with the general idea. Note that I have a shader which spends 
5s in copy_propagate()... That's huge! Looks like this series might 
improve the situation here, but needs more testing.

Thanks!
