The Vulkan 1.1.81 spec says:
"It is legal for offset.x + extent.width or offset.y + extent.height
to exceed the dimensions of the framebuffer - the scissor test still
applies as defined above. Rasterization does not produce fragments
outside of the framebuffer, so such fragments never have the scissor
test performed on them."
Elsewhere, the Vulkan 1.1.81 spec says:
"The application must ensure (using scissor if necessary) that all
rendering is contained within the render area, otherwise the pixels
outside of the render area become undefined and shader side effects
may occur for fragments outside the render area. The render area
must be contained within the framebuffer dimensions."
Unfortunately, there's some room for interpretation here as to what the
consequences are of having the render area set to exactly the
framebuffer dimensions and having a scissor that is larger than the
framebuffer. Given that GL and other APIs provide automatic clipping to
the framebuffer, it makes sense that applications would assume that
Vulkan does this as well. It costs us very little to play it safe and
just clamp client-provided scissors to the framebuffer dimensions.
Fortunately, the user is required to provide us with at least one
scissor so we don't need to handle the case where they don't.

This is the second patch needed to fix the following piglit tests:

tests/spec/arb_gl_spirv/linker/uniform/multisampler-array.shader_test
Although in this case it doesn't affect so many borrowed tests, as
there aren't too many tests using multisamplers on Intel.
It is worth to note that this patch is also needed when those tests
are run on GLSL mode (using the --glsl option). Although most Intel
drivers would not be able to run/execute tests using multisamplers, as
GL_MAX_IMAGE_SAMPLES is zero, technically those tests are expected to
link correctly, so linking tests should pass.

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

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.
