The new encoding returns a value via the 2nd src. The legalize pass
needs to be aware of this to set the correct needs_sy flag, otherwise we
can, in cases where the atomic dst is not used, overwrite the register
that hardware will asynchronously load result into without (sy) flag, so
it gets clobbered by the atomic result.
This fixes a whole lot of rando ssbo+atomic fails, like
dEQP-GLES31.functional.ssbo.layout.single_basic_type.packed.highp_vec4.

It seems like some instructions (noticed this w/ cat3), cannot read HIGH
regs.. cat1 (mov/cov) can, and possibly some/all of cat2.
The blob seems to stick w/ an extra mov into low regs. So lets do the
same.
This fixes WGID on a6xx, which unsurprisingly is related to a lot of

Images and SSBOs don't map directly to the hw. They end up being part
texture and part something else. Starting with a6xx, the hack used for
a5xx to smash the image tex state into hw texture state starting from
MAX counting down won't work, because we start using tex state also for
SSBO read.

If nothing else, this will make problems with cmdstream getting blit
over with pixels easier to track down (ie. faults when it first happens
rather than strange failures later from corrupted cmdstream when a
stateobj is later reused).
(NOTE this somewhat depends on the kernel supporting the flag, and the
iommu implementation. But the worst case is just that the cmdstream
ends up writeable as before.)

the naming is a bit confusing no matter how you look at it. Within SPIR-V
"global" memory is memory accessible from all threads. glsl "global" memory
normally refers to shader thread private memory declared at global scope. As
we already use "shared" for memory shared across all thrads of a work group
the solution where everybody could be happy with is to rename "global" to
"private" and use "global" later for memory usually stored within system
accessible memory (be it VRAM or system RAM if keeping SVM in mind).
glsl "local" memory is memory only accessible within a function, while SPIR-V
"local" memory is memory accessible within the same workgroup.

Fixes the following crash that happened after d6110d4d
The problem happens if we first compile a "vanilla" shader with nothing
lowered in NIR, which perform the final lowering passes on so->shader->
nir (including nir_lower_locals_to_regs()), and then later we have
compile a shader with some lowering. The second time through we would
have already done nir_lower_locals_to_regs().
Arguably this was already a bug, just one we hadn't noticed yet.

emit_intrinsic_store_image() is always using 4 components when
collecting registers for the value. When image has less than
4 components (e.g, r32f, rg32i, etc) this results in extra mov
instructions.
This patch uses the actual number of components from the image format.
For example, in a shader like:
layout (r32f, binding=0) writeonly uniform imageBuffer u_image;
...
void main(void) {
...
imageStore (u_image, some_offset, vec4(1.0));
...
}
instruction count is reduced in at least 3 instructions (note image
format is r32f, 1 component only).
This obviously reduces register pressure as well.
v2: - Added support for image formats from NV_image_format extension
(Ilia Mirkin).
- Return 4 components by default instead of asserting. (Rob Clark).
v3: Added more missing formats (Ilia Mirkin).
v4: Added a debug message for unknown image formats (Rob Clark).
