For whatever reason, we had an INTEL_DEBUG=stats option that enabled
various statistics counters on Gen4-5 systems. It's been around
forever, though I can't think of a single time that it's been useful.
On Gen6+, we enable statistics all the time because they're necessary
to support various query object targets. Turning them off would break
those queries.
Gen4-5 don't support those queries, so the statistics counters generally
aren't useful; we disabled them by default. This patch disables them
altogether.

We apparently enabled this on all platforms in Mesa 10.6. However, it
was only ever implemented for Gen6+. The Gen4-5 query code goes up in
flames with an "Unrecognized query target" unreachable() error if you
even attempt to use any of the new functionality.
This wasn't caught because the Piglit tests require OpenGL 3.0, which
Gen4-5 cannot support. The extension spec does say 3.0 is required,
though I'm not sure why - it seems like 2.1 would work fine.
We could implement it anyway, but it's a little bit of a pain due to the
lack of hardware contexts (so we have to snapshot around batches).
Given that it's been 100% broken for two years and I haven't seen a bug
report about it, I'm not terribly inclined to care. So, let it go.

The function was pretty slow. This brings a substantial decrease in draw
call overhead when min/max index bounds are not needed:
Before: DrawElements (1 VBO) w/ no state change: 5.75 million
After: DrawElements (1 VBO) w/ no state change: 7.03 million

pipe_draw_info::indexed is replaced with index_size. index_size == 0 means
non-indexed.
Instead of pipe_index_buffer::offset, pipe_draw_info::start is used.
For indexed indirect draws, pipe_draw_info::start is added to the indirect
start. This is the only case when "start" affects indirect draws.
pipe_draw_info::index is a union. Use either index::resource or
index::user depending on the value of pipe_draw_info::has_user_indices.
v2: fixes for nine, svga
Similar to how image resources are handled. That way we are sure
that inst->resource.file is PROGRAM_SAMPLER for "bound" samplers.

The NIR pass already handles remapping system values to attributes for
us so we delete the system value code as part of the conversion.
We also change nir_lower_vs_inputs to take an explicit inputs_read
bitmask and pass in the inputs_read from prog_data instead from pulling
it out of NIR. This is because the version in prog_data may get
EDGEFLAG added to it on some old platforms.

Commit e1af20f18a changed the shader_info
from being embedded into being just a pointer. The idea was that
sharing the shader_info between NIR and GLSL would be easier if it were
a pointer pointing to the same shader_info struct. This, however, has
caused a few problems:
1) There are many things which generate NIR without GLSL. This means
we have to support both NIR shaders which come from GLSL and ones
that don't and need to have an info elsewhere.
2) The solution to (1) raises all sorts of ownership issues which have
to be resolved with ralloc_parent checks.
3) Ever since 00620782c9, we've been
using nir_gather_info to fill out the final shader_info. Thanks to
cloning and the above ownership issues, the nir_shader::info may not
point back to the gl_shader anymore and so we have to do a copy of
the shader_info from NIR back to GLSL anyway.
All of these issues go away if we just embed the shader_info in the
nir_shader. There's a little downside of having to copy it back after
calling nir_gather_info but, as explained above, we have to do that
anyway.
