r600g: Implement POLYGON_OFFSET_UNITS_UNSCALED
Empirical tests show that the polygon offset

the polygon offset formula, and setting 0 for

On MRF platforms, we need to set base_mrf to the first MRF value we'd
like to use for the message. On send-from-GRF platforms, we set it to
-1 to indicate that the operation doesn't use MRFs.
As MRF platforms are becoming increasingly a thing of the past, we've
forgotten to bother with this. It makes more sense to set it to -1 by
default, so we don't have to think about it for new code.
I searched the code for every instance of 'mlen =' in brw_fs*cpp, and
it appears that all MRF-based messages correctly program a base_mrf.
Forgetting to set base_mrf = -1 can confuse the register allocator,
causing it to think we have a large fake-MRF region. This ends up
moving the send-with-EOT registers earlier, sometimes even out of
the g112-g127 range, which is illegal. For example, this fixes
illegal sends in Piglit's arb_gpu_shader_fp64-layout-std430-fp64-shader,
which had SSBO messages with mlen > 0 but base_mrf == 0.

i965: Implement rasterizer discard via SOL unless required for queries.
We currently use CL_INVOCATION_COUNT for the GL_PRIMITIVES_GENERATED
query, which involves passing all primitives to the clipper. When
rasterizer discard is enabled, we program the clipper in REJECT_ALL
mode, rather than using the SOL stage's "Rendering Disable" feature.
See commit
f09b91f78247409f54c975f56cb10d5f350fe64e for an explanation
of why we implement GL_PRIMITIVES_GENERATED this way.
Apparently the SOL stage's "Rendering Disable" feature is a lot faster
than having the clipper reject all primitives. It's safe to use when
no GL_PRIMITIVES_GENERATED query is active, as we don't care about
CL_INVOCATION_COUNT incrementing.
This patch makes us use SO_RENDERING_DISABLE when no query is active,
but continues falling back to the clipper in REJECT_ALL mode when the
queries are enabled. It brings back the perf_debug for the clipper
case (which I removed in commit
1f9445ff57b, thinking it wasn't useful).

Constant propagation on arrays doesn't make a lot of sense. If the
array is only accessed with constant indexes, then opt_array_splitting
would split it up. Otherwise, we have variable indexing. If there's
multiple accesses, then constant propagation would end up replicating
the data.
The lower_const_arrays_to_uniforms pass creates uniforms for each
ir_constant with array type that it encounters. This means that it
creates redundant uniforms for each copy of the constant, which means
uploading too much data. It can even mean exceeding the maximum number
of uniform components, causing link failures.
We could try and teach the pass to de-duplicate the data by hashing
constants, but it makes more sense to avoid duplicating it in the first
place. We should promote constant arrays to uniforms, then propagate
the uniform access.
Fixes the TressFX shaders from Tomb Raider, which exceeded the maximum
number of uniform components by a huge margin and failed to link.
On Broadwell:
total instructions in shared programs:
9067702 ->
9068202 (0.01%)
instructions in affected programs: 10335 -> 10835 (4.84%)
helped: 10 (Hoard, Shadow of Mordor, Amnesia: The Dark Descent)
HURT: 20 (Natural Selection 2)
loops in affected programs: 4 -> 0
The hurt programs appear to no longer have a constarray uniform, as
all constants were successfully propagated. Apparently before this
patch, we successfully unrolled a loop containing array access, but
only after promoting constant arrays to uniforms. With this patch,
we unroll it first, so all array access is direct, and the array
is split up, and individual constants are propagated. This seems
better.

glsl: Split arrays even in the presence of whole-array copies.
Previously, we failed to split constant arrays. Code such as
int[2] numbers = int[](1, 2);
would generates a whole-array assignment:
(assign () (var_ref numbers)
(constant (array int 4) (constant int 1) (constant int 2)))
opt_array_splitting generally tried to visit ir_dereference_array nodes,
and avoid recursing into the inner ir_dereference_variable. So if it
ever saw a ir_dereference_variable, it assumed this was a whole-array
read and bailed. However, in the above case, there's no array deref,
and we can totally handle it - we just have to "unroll" the assignment,
creating assignments for each element.
This was mitigated by the fact that we constant propagate whole arrays,
so a dereference of a single component would usually get the desired
single value anyway. However, I plan to stop doing that shortly;
early experiments with disabling constant propagation of arrays
revealed this shortcoming.
This patch causes some arrays in Gl32GSCloth's geometry shaders to be
split, which allows other optimizations to eliminate unused GS inputs.
The VS then doesn't have to write them, which eliminates the entire VS
(5 -> 2 instructions). It still renders correctly.
No other change in shader-db.

glsl: Make constant propagation's folder not propagate into an LHS.
opt_constant_propagation.cpp contains constant folding code which can
actually do constant propagation in some cases. It was happily
propagating constants into the left-hand-side of assignments.
For example,
(assign () (var_ref temp) (constant ...))
would brilliantly be turned into:
(assign () (constant ...) (constant ....))
This is a bigger hammer than necessary - it prevents propagation
into the left-hand-side altogether. We could certainly do better
someday. Notably, the constant propagation pass itself already
takes this approach - it's just the constant propagation pass's
built-in constant folding code (which actually propagates, too)
that was broken.
No change in shader-db, but prevents regressions after future commits.
It seems plausible that this could be hit today, but I haven't seen it
happen.
