There is no good reason why we should have the same logic repeated in
get_vulkan_resource_index and vtn_ssa_offset_pointer_dereference. If
we're a bit more careful about how we do things, we can just use the one
function and get rid of the other entirely. This also makes the push
constant special case a lot more clear.

We should use the result type of the OpSampledImage opcode, rather than
the type of the underlying image/samplers.
This resolves an issue when using separate images and shadow samplers
with glslang. Example:
layout (...) uniform samplerShadow s0;
layout (...) uniform texture2D res0;
...
float result = textureLod(sampler2DShadow(res0, s0), uv, 0);
For this, for the combined OpSampledImage, the type of the base image
was being used (which does not have the Depth flag set, whereas the
result type does), therefore it was not being recognised as a shadow
sampler. This led to the wrong LLVM intrinsics being emitted by RADV.

Now that we have a pointer wrapper class, we can create offsets for UBOs

Everyone now calls it with stop_at_matrix = false. Since we're now

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.

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.

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.

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.

Once again, SPIR-V is insane... It allows you to place "patch"
decorations on structure members. Presumably, this is so that you can
do something such as
out struct S {
layout(location = 0) patch vec4 thing1;
layout(location = 0) vec4 thing2;
} str;
And have your I/O "nicely" organized. While this is a bit silly, it's
allowed and well-defined so whatever. Where it really gets interesting
is when you have an array of struct. SPIR-V says nothing about not
allowing you to have those qualifiers on the members of a struct that's
inside an array and GLSLang does this. Specifically, if you have
layout(location = 0) out patch struct S {
vec4 thing1;
vec4 thing2;
} str[2];
then GLSLang will place the "patch" decorations on the struct members.
This is ridiculous there is no way that having some of them be patch and
some not would be well-defined given that patch and non-patch outputs
are in effectively different storage classes. This commit moves around
the way we handle the "patch" decoration so that we can detect even the
crazy cases and handle them.
