5b1b088f2a nir/spirv: fix chain access with different index bit sizes
Currently we support 32-bit indexes/offsets all over the driver, so we
convert them to that bit size.

Fixes dEQP-VK.spirv_assembly.instruction.*.indexing.*

v2: Use u2u32 instead (Jason).

6d30f33307 nir/spirv: Simplify matrix loads/stores
Instead of handling all of the complexity at the end, we choose to
decorate types a bit more cleverly.  When we have a row-major matrix
type, we give it the stride of a single vector and give it's array
element type (which represents a column) the actual matrix stride.

Previously, we were using stop_at_matrix and handling everything from
matrix on down as special cases but now we walk the access chain all the
way to the end and then load.  Even though this looks like it may lead
to a significant functional change, it doesn't.  The reason why we
needed to do stop_at_matrix before was to handle row-major properly
since the offsets and strides would be all out-of-order.  Now that row
major matrix types have the small stride on the matrix and the large
stride on the vector, offsetting to a single column of a row-major
matrix works fine.  The load/store code simply picks up on the fact that
the stride isn't the type size and does multiple loads.  The generated
code from these methods should be the same.

415e198d48 nir/spirv: Wrap access chains in a new vtn_pointer data structure
The vtn_pointer structure provides a bit better abstraction than passing
access chains around directly.  For one thing, if the pointer just
points to a variable, we don't need the access chain at all.  Also,
pointers know what their dereferenced type is so we can avoid passing
the type in a bunch of places.  Finally, pointers can, in theory, be
extended to the case where you don't actually know what variable is
being referenced.

196e6b60b1 spirv: fix OpBitcast when the src and dst bitsize are different (v3)
Before, we were just implementing it with a move, which is incorrect
when the source and destination have different bitsizes. To implement
it properly, we need to use the 64-bit pack/unpack opcodes. Since
glslang uses OpBitcast to implement packInt2x32 and unpackInt2x32, this
should fix them on anv (and radv once we enable the int64 capability).

v2: make supporting non-32/64 bit easier (Jason)
v3: add another assert (Jason)

1bd0acab21 spirv: Work around the Doom shader bug
Doom shipped with a broken version of GLSLang which handles samplers as
function arguments in a way that isn't spec-compliant.  In particular,
it creates a temporary local sampler variable and copies the sampler
into it.  While Dave has had a hack patch out for a while that gets it
working, we've never landed it because we've been hoping that a game
update would come out with fixed shaders.  Unfortunately, no game update
appears on to be on the horizon and I've found this issue in yet another
application so I think we're stuck working around it.  Hopefully, we can
delete this code one day.

b86dba8a0e nir: Embed the shader_info in the nir_shader again
Commit e1af20f18a changed the shader_info
from being embedded into being just a pointer.  The idea was that
sharing the shader_info between NIR and GLSL would be easier if it were
a pointer pointing to the same shader_info struct.  This, however, has
caused a few problems:

 1) There are many things which generate NIR without GLSL.  This means
    we have to support both NIR shaders which come from GLSL and ones
    that don't and need to have an info elsewhere.

 2) The solution to (1) raises all sorts of ownership issues which have
    to be resolved with ralloc_parent checks.

 3) Ever since 00620782c9, we've been
    using nir_gather_info to fill out the final shader_info.  Thanks to
    cloning and the above ownership issues, the nir_shader::info may not
    point back to the gl_shader anymore and so we have to do a copy of
    the shader_info from NIR back to GLSL anyway.

All of these issues go away if we just embed the shader_info in the
nir_shader.  There's a little downside of having to copy it back after
calling nir_gather_info but, as explained above, we have to do that
anyway.
