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.
If you are interested you can use this [1] shader-db patch to find
problem shaders.
Note: The compile times returned from that patch seem to work most of
the time but occasionally it returns negative times so I've obviously
got a bug in there somewhere.
This one fixes the bug just in case anyone looks at this:

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%.
