spirv: Ignore ArrayStride in OpPtrAccessChain for Workgroup
From OpPtrAccessChain description in the SPIR-V spec (1.4 rev 1):
For objects in the Uniform, StorageBuffer, or PushConstant storage
classes, the element’s address or location is calculated using a
stride, which will be the Base-type’s Array Stride when the Base
type is decorated with ArrayStride. For all other objects, the
implementation will calculate the element’s address or location.
For non-CL shaders the driver should layout the Workgroup storage
class, so override any explicitly set ArrayStride in the shader. This
currently fixes only the lower_workgroup_access_to_offsets case, which
is used by anv.

We implement GLES3.0 instanced rendering with full support for instanced
arrays (via instance divisors). To do so, we use the new invocation
helpers to invoke a triplet of (1, vertex_count, instance_count), rather
than simply (1, vertex_count, 1). We rewrite the attribute handling code
into a new pan_instancing.c file which handles both the simple LINEAR
case for non-instanced as well as each of the new instancing cases:
MODULO (for per-vertex attributes), POT and NPOT divisors.
As a side effect, we rework how vertex buffers are handled, duplicating
them to be 1:1 with vertex descriptors to simplify instancing code paths
dramatically. This might be a performance regression, but this remains
to be seen; if so, we can always deduplicate later with some added logic
in pan_instancing.c

nir/linker: add gl_nir_link_uniform_blocks.c
Adding the ability to link uniform blocks and shader storage blocks
using NIR, intended for ARB_gl_spirv support. Among other things, this
linking needs to take into account that everything should work without
names, as they could be not present, while the GLSL IR uniform block
linking was wrote with the names on its core.
The other major difference compared with the GLSL IR linker is that we
don't deal with layouts. There are no references to std140, std430,
etc. Layouts are expressed through explicit offset, array stride and
matrix stride. That simplifies how the buffer size are computed. But
also means that we couldn't use the existing methods at glsl_types, so
we needed to implement new methods.
It is worth to note that this linking do a iteration over the
glsl_types, similarly to what the linking uniforms do. A possible
future improvement would be refactor both cases to try to share more
code that it sharing right now. On GLSL IR there are a class visitor,
specialized on each case, for that sharing. As adding a class visitor
on C would more complicated, for now we are just iterating on both.
