I'm a bit surprised it's that slow... do you have any idea what's going
on? I've made flamegraphs in the past on i965 to see where most of the
time is spent.
Some shaders are actually faster, but things like the Deus Ex shaders
(and looks like especially the dolphin uber shaders are slower).
With the Deus Ex shaders I was looking at we spend 20% in opt_algebraic
and before this series 7.2% in nir_opt_cse (after this series 4.9%). The
shaders have lots of operations converting vales to different type etc.

Currently the radeonsi NIR backend takes around twice the time
of the tgsi backend to compile shader-db. These are some first
steps at reducing the overhead of NIR.
This series reduces the compile time of a Deus Ex program I was
profiling by around 5%.
