Previously, each shader took 3 shader time indices which were potentially
at arbirary points in the shader time buffer. Now, each shader gets a
single index which refers to 3 consecutive locations in the buffer. This
simplifies some of the logic at the cost of having a magic 3 a few places.

This creates the options at screen cration time and then we just copy them
into the context at context creation time. We also move is_scalar to the
brw_compiler structure.
We also end up manually setting some values that the core would have set by
default for us. Fortunately, there are only two non-zero shader compiler
option defaults that we aren't overriding anyway so this isn't a big deal.

On gen9+ MOCS is an index into a table. It is 7 bits, and AFAICT, bit 0 is for
doing encrypted reads.
I don't recall how I decided to do this for BXT. I don't know this patch was
ever needed, since it seems nothing is broken today on SKL. Furthermore, this
patch may no longer be needed because of the ongoing changes with MOCS setup. It
is what is being used/tested, so it's included in the series.
The chosen values are the old values left shifted. That was also an arbitrary
choice.
v2: Use shift in MOCS to make it clear what we're doing. (Ken)

This implements a workaround (exact excerpt as a comment in the code). The docs
specify [clearly, after you struggle for a while] that the offset isn't relative
to state base. This actually makes sense. This fixes hangs on SKL.
Buffer #0 is meant to be used for normal uniforms.
Buffer #1 is typically used for gather constants when using RS.
Buffer #1-#3 could be used to push a bunch of UBO data which would just be
somewhere in memory, and not relative to the dynamic state.
NOTE: I've moved away from the ternary operator for the new gen9 conditions.
Admittedly it's probably not great to do this, but I really want to fix this all
up in the subsequent patch and doing it here makes that diff a lot nicer. I want
to split out the gen8/9 code to make the function a bit more readable, but to
keep this easily cherry-pickable I am doing this fix first. If we decide not to
merge the cleanup patch then I can revisit this.

Freedreno needs sampler type information to deal with int/uint textures.
To accomplish this, start creating sampler-view declarations, as
suggested here:
http://lists.freedesktop.org/archives/mesa-dev/2014-November/071583.html
create a sampler-view with index matching the sampler, to encode the
texture type (ie. SINT/UINT/FLOAT). Ie:
DCL SVIEW[n], 2D, UINT
DCL SAMP[n]
TEX OUT[1], IN[1], SAMP[n]
For tgsi texture instructions which do not take an explicit SVIEW
argument, the SVIEW index is implied by the SAMP index.

The original code meant to do this, but was only checking num_samples == 1 to
figure out if a surface was fast clear capable. However, we can allocate single
sample miptrees with num_samples == 0 (when it's an internally created buffer).
This fixes a bunch of the piglit tests on gen8. Other gens should have been
fine.
Here is the order of events that allowed this to slip through:
t0: I wrote halign patches and tested them. These alignment assertions are for
gen8 fast clear surfaces, basically.
t1: I pushed bogus perf patch which made fast clears never happen
t2: Reworked halign patches based on Chad's feedback and introduced the bug this
patch fixes.
t2.5: I tested reworked patches, but assertion wasn't hit because of t1.
t3. Matt fixed issue in t1 which made fast clears happen here:

We can't use sampler messages with gradient information (like
sample_g or sample_d) to deal with this scenario because according
to the PRM:
"The r coordinate and its gradients are required only for surface
types that use the third coordinate. Usage of this message type on
cube surfaces assumes that the u, v, and gradients have already been
transformed onto the appropriate face, but still in [-1,+1] range.
The r coordinate contains the faceid, and the r gradients are ignored
by hardware."
Instead, we should lower this to compute the LOD manually based on the
gradients and use a different sample message that takes the computed
LOD instead of the gradients. This is already being done in
brw_lower_texture_gradients.cpp, but it is restricted to shadow
samplers only, although there is a comment stating that we should
probably do this also for samplerCube and samplerCubeArray.
Because of this, both dEQP and Piglit test cases for textureGrad with
cube maps currently fail.
This patch does two things:
1) Activates the texturegrad lowering pass for all cube samplers.
2) Corrects the computation of the LOD value for cube samplers.
I had to do 2) because for cube maps the calculations implemented
in the lowering pass always compute a value of rho that is twice
the value we want (so we get a LOD value one unit larger than we
want). This only happens for cube map samplers (all kinds). I am
not sure about why we need to do this, but I suspect that it is
related to the fact that cube map coordinates, when transported
to a specific face in the cube, are in the range [-1, 1] instead of
[0, 1] so we probably need to divide the derivatives by 2 when
we compute the LOD. Doing that would produce the same result as
dividing the final rho computation by 2 (or removing a unit
from the computed LOD, which is what we are doing here).
Fixes the following piglit tests:
bin/tex-miplevel-selection textureGrad Cube -auto -fbo
bin/tex-miplevel-selection textureGrad CubeArray -auto -fbo
bin/tex-miplevel-selection textureGrad CubeShadow -auto -fbo

Previously when setting up the sample instruction for an indirect
sampler the vec4 backend was directly passing the pseudo opcode's
src0. However vec4_visitor::visit(ir_texture *) doesn't set the
texture operation's src0 -- it's left as BAD_FILE, which when
translated into a brw_reg gives the null register. In brw_SAMPLE,
gen6_resolve_implied_move() inserts a MOV from the inst->base_mrf and
sets the src0 appropriately. The indirect sampler case did not have a
call to gen6_resolve_implied_move().
The fs backend avoids this because the platforms that support dynamic
indexing of samplers (IVB+) have been converted to not use the
fake-MRF hack, and instead send from proper GRFs.
This patch makes it call gen6_resolve_implied_move before setting up
the indirect message. This is similar to what is done for constant
sampler numbers in brw_SAMPLE.
The Piglit tests for sampler array indexing didn't pick this up
because they were using a texture with a solid colour so it didn't
matter what texture coordinates were actually used. The tests have now
been changed to be more thorough in this commit:
http://cgit.freedesktop.org/piglit/commit/?id=4f9caf084eda7
With that patch the tests for gs and vs are currently failing on
Ivybridge, but this patch fixes them. There are no other changes to a
Piglit run on Ivybridge.
On Skylake the gs tests were failing even without the Piglit patch
because Skylake needs the source registers to work correctly in order
to send a message header to select SIMD4x2 mode.

Turner)
