The spec seems clear this is not allowed but the Nvidia binary
forces apps to add layout qualifiers so this works around the
issue for No Mans Sky until the CTS can be sorted out.

The spec is quite clear this is not allowed:
From Section 4.4. (Layout Qualifiers) of the GLSL 4.60 spec:
"Layout qualifiers can appear in several forms of declaration.
They can appear as part of an interface block definition or
block member, as shown in the grammar in the previous section.
They can also appear with just an interface-qualifier to establish
layouts of other declarations made with that qualifier:
layout-qualifier interface-qualifier ;
Or, they can appear with an individual variable declared with
an interface qualifier:
layout-qualifier interface-qualifier declaration ;"
From Section 4.10 (Memory Qualifiers) of the GLSL 4.60 spec:
"Layout qualifiers cannot be used on formal function parameters,
and layout qualification is not included in parameter matching."
However on the Nvidia binary driver they actually fail to compile
if image function params don't have a layout qualifier. This results
in applications such as No Mans Sky using layout qualifiers on params.
I've submitted a CTS test to expose this problem in the Nvidia driver
but until that is resolved this patch will help Mesa drivers work
around the issue.

Now that the drivers are lowering to surface indices themselves, we no
longer need to push the surface index into the shader.

Previously, the back-end compiler turn image access into magic uniform
reads and there was a complex contract between back-end compiler and
driver about setting up and filling out those params. As of this
commit, both drivers now lower image_deref_load_param_intel intrinsics
to load_uniform intrinsics controlled by the driver and lower the other
image_deref_* intrinsics to image_* intrinsics which take an actual
binding table index. There are still "magic" uniforms but they are now
added and controlled entirely by the driver and that contract no longer
spans components.
This also has the side-effect of making most image use compile-time
binding table indices. Previously, all image access pulled the binding
table index from a uniform. Part of the reason for this was that the
magic uniforms made it difficult to decouple binding table indices from
the uniforms and, since they are indexed completely differently
(especially in Vulkan), it was hard to pull them apart. Now that the
driver is handling both, it's trivial to decouple the two and provide
actual binding table indices.

This commit expands the current memory access enum to contain the extra
two bits provided for images. We choose to follow the SPIR-V convention
of NonReadable and NonWriteable because readonly implies that you *can*
read so readonly + writeonly doesn't make as much sense as NonReadable +
NonWriteable.
Reviewed-by: Kenneth Graunke <kenneth@whitecape.org>
The GLSL spec allows you to set both the "readonly" and "writeonly"
qualifiers on images to indicate that it can only be used with
imageSize. However, we had no way of representing this int he linked
shader and flagged it as GL_READ_ONLY. This is good from a "does it use
this buffer?" perspective but not from a format and access lowering
perspective. By using GL_NONE for if "readonly" and "writeonly" are
both set, we can detect this case in the driver and handle it correctly.
Nothing currently relies on the type of surface in the "readonly" +
"writeonly" case but that's about to change. i965 is the only drier
which uses the ImageAccess field and gl_bindless_image::access is
currently unused.

Having the array length component stored in .z was a small convenience
for the ISL image param filling code and an annoyance in the NIR
lowering code. The only convenience of treating 1D arrays like 2D
arrays in the lowering code is in the address calculation code so let's
put all the complexity there as well.

This commit moves our storage image format conversion codegen into NIR
instead of doing it in the back-end. This has the advantage of letting
us run it through NIR's optimizer which is pretty effective at shrinking
things down. In the common case of rgba8, the number of instructions
emitted after NIR is done with it is half of what it was with the
lowering happening in the back-end. On the downside, the back-end's
lowering is able to directly use predicates and the NIR lowering has to
use IFs.

Instead of requiring 4 components, this allows them to potentially use

The flag_rect and flag_buffer fields didn't sufficiently capture
the state changes needed for those resource types. For example,
if a texture binding was changed from a 500x500 rect texture to a
400x400 rect texture we didn't set SVGA_NEW_TEXTURE_CONSTS. But
we need to do that to emit the new texcoord scale factors to the
constant buffers. Rather than track the sizes of all bound
resources, just set the flag if the resource is a rect. Same
story with texture buffers.
Also, since rect/buffer textures are usable with VS/GS shaders,
add SVGA_NEW_TEXTURE_CONSTS to the flags we check for emitting
VS/GS constants.
This seems to help with XFCE / xfwm4 desktop scaling.
