iris: Drop PIPE_CAP_BUFFER_SAMPLER_VIEW_RGBA_ONLY
This cap is mainly for working around a r600 texture swizzle issue,
but it also controls whether ARB_texture_buffer_object (with legacy
formats) is enabled. I suspect the missing I/L/A/LA faking is why
I had it set in the first place.
Thanks to Ilia for pointing out that I shouldn't be setting this.

iris: Properly support alpha and luminance-alpha formats
For texturing, we map alpha formats to the corresponding red format,
as many alpha formats are outright missing, and red is more efficient
when sampling anyway.
When rendering to A8_UNORM, we use that format directly, so the image
gets the shader output's .a/.w channel, rather than the .r/.x channel.
All other A* formats are non-renderable, so we can't do much and just
mark them as unsupported for rendering. Fortunately, GL only requires
rendering to A8_UNORM, so that works out.
According to Andre Heider and Timur Kristóf, this fixes font rendering
in Witcher 1 (via nine). Andre also reported that it fixes Unigine
Heaven (presumably via nine).
v2: Use the same swizzle for both sampler views and "render targets".
BLORP expects the read swizzle, and will take the inverse when
setting up the destination swizzle (and actually applying it in
the shaders). We ignore the format swizzle when setting up normal
rendering SURFACE_STATEs, which is necessary because it would be
an illegal shader channel select combination. Thanks to Jason
Ekstrand for pointing out that BLORP took an inverse swizzle.

iris: Defer uploading sampler state tables until draw time
Gallium might call us multiple times to bind subsets of the samplers,
at which point we'd recreate the table a bunch of times. It doesn't
really buy us anything to do it here - even if we defer to draw time,
the dirty tracking ensures we'll only do it on the first draw after a
bind_sampler_states() call.
We now use the number of samplers specified by the shader instead of
the binding count. If this number changes, we flag sampler state as
dirty so we re-upload a table with the right number of entries.
This also fixes a bug where ice->state.need_border_colors was never
unset, so once something needed border colors, the pool would always
be pinned in all future batches.
v2: Explicitly flag sampler states as dirty, rather than assuming that
bind_sampler_states() will be called if the program texture count
changes. While this may be true for st/mesa, it isn't the case for
Gallium HUD.

st/glsl: start spilling out common st glsl conversion code
The NIR and TGSI paths are currently intertwined which makes it

Here we take the first step to splitting that path apart. With
this we take the opportunity to no longer call the GLSL IR
optimisation passes after the final lowering calls for NIR. We
can instead just use the NIR passes which can produce better code
and should also result in faster compile times.
The speed-up can be measured in some dolphin uber shaders due to
no longer calling lower_if_to_cond_assign() for example
dolphin/ubershaders/120.shader_test goes from ~1.63 -> ~1.53

There are some code changes as a result of not calling
lower_if_to_cond_assign(), this is because it flattens ifs that

nir: Teach loop unrolling about 64-bit instruction lowering
The lowering we do for 64-bit instructions can cause a single NIR ALU
instruction to blow up into hundreds or thousands of instructions
potentially with control flow. If loop unrolling isn't aware of this,
it can unroll a loop 20 times which contains a nir_op_fsqrt which we
then lower to a full software implementation based on integer math.
Those 20 invocations suddenly get a lot more expensive than NIR loop
unrolling currently expects. By giving it an approximate estimate
function, we can prevent loop unrolling from going to town when it
shouldn't.

nir: Move nir_lower_uniforms_to_ubo to compiler/nir.
The nir_lower_uniforms_to_ubo function is useful outside of
mesa/state_tracker, and in fact is needed to produce NIR for
drivers that have the PIPE_CAP_PACKED_UNIFORMS capability.

tgsi_to_nir: Split to smaller functions.
Previously, tgsi_to_nir was a single big function, and this patch
intends to make the code easier to understand by splitting it up
to multiple smaller pieces.

tgsi_to_nir: Fix TGSI LIT translation by using flt.
TGSI spec says LIT needs a "greater than" comparison. NIR doesn't have that,
so let's use "less than" and swap the arguments. Previously "greater than or equal"
was used by tgsi_to_nir which is incorrect.

tgsi_to_nir: Fix the TGSI ARR translation by converting the result to int.
According to the TGSI spec, ARR needs to do a rounding and then
a float-to-integer conversion which was missing. This patch also
makes the rounding a bit more efficient by using nir_fround_even
instead of the previous nir_ffloor+nir_fadd trick.

nir: Add ability for shaders to use window space coordinates.
This patch adds a shader_info field that tells the driver to use window
space coordinates for a given vertex shader. It also enables this feature
in radeonsi (the only NIR-capable driver that supported it in TGSI),
and makes tgsi_to_nir aware of it.

v3d: Move the stores for fixed function VS output reads into NIR.
This lets us emit the VPM_WRITEs directly from
nir_intrinsic_store_output() (useful once NIR scheduling is in place so
that we can reduce register pressure), and lets future NIR scheduling
schedule the math to generate them. Even in the meantime, it looks like
this lets NIR DCE some more code and make better decisions.
