If there is a 4-byte hole between 2 loads, they are vectorized. Example:
load 4 + hole 4 + load 8 -> load 16
This helps GLSL uniform loads, which are often sparse. See the code for more
info.
RADV could get better code by vectorizing later.

This should have no effect on LLVM because ac_build_buffer_load scalarizes
SMEM, but it's improved for some reason:

There is nothing preventing ACO from generating loads with unused
components. This happens often with GLSL uniforms. Some of those loads
are partially re-vectorized after this.

Walk the whole vertex stride thanks to XFB info sorted by offset, gather
individual components from same or different outputs, and once we have
gathered 4, store them as vec4.
It also removes the memory_modes field from VMEM stores because I don't
think it's needed.

The mesa crate should just provide the means of creating those, but the
logic of what to create shouldn't be there.
The passed in arguments also heavily vary, and this way we can be explicit
about what variants needs what inputs.

This allows us to use more contextual information of the image to create
the pipe_sampler_view properly instead of passing all the required
properties via function arguments.

This simplifies sampler view tracking a bit for us. Also, drivers will
automatically free the pipe_sampler_view as well.
It was wrong to call into sampler_view_destroy directly anyway, because
pipe_sampler_view is a refcounted object and pipe_sampler_view_reference
should be used instead.

I stumbled on this limit - it turns out that large local_sizes apply an
additonal limit on gprs per thread. If we violate this limit, then dmesg
just gives us a rather unhelpful message that the channel is killed:
