intel_asm_annotation.c is part of libintel_compiler.la, which contains
code for disassembling and validating shaders that we want to call in
aubinator_error_decode.
dump_assembly() calls nir_print_instr() to print annotations, and
although dump_assembly() is not called by aubinator_error_decode (nor is
any function in intel_asm_annotation.c) it causes undefined references
to nir_print_instr().
To work around, provide a no-op weak symbol to resolve against.
This will allow the validator to run on shader programs we find in the
GPU hang error state.

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.

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.

Now that we can allocate states larger than the block size, we no longer
need a block size of 1MB which can be rather wasteful.
Reviewed-by: Juan A. Suarez Romero <jasuarez@igalia.com>
Previously, the maximum size of a state that could be allocated from a
state pool was a block. However, this has caused us various issues
particularly with shaders which are potentially very large. We've also
hit issues with render passes with a large number of attachments when we
go to allocate the block of surface state. This effectively removes the
restriction on the maximum size of a single state. (There's still a
limit of 1MB imposed by a fixed-length bucket array.)
For states larger than the block size, we just grab a large block off of
the block pool rather than sub-allocating. When we go to allocate some
chunk of state and the current bucket does not have state, we try to
pull a chunk from some larger bucket and split it up. This should
improve memory usage if a client occasionally allocates a large block of
state.
This commit is inspired by some similar work done by Juan A. Suarez
Romero <jasuarez@igalia.com>.
