This patch makes index expressions on resources hlsl_ir_index nodes
instead of hlsl_ir_resource_load nodes, because it is not known if they
will be used later as the lhs of an hlsl_ir_resource_store.
For now, the only benefit is consistency.
Otherwise, in the added test, we get:
vkd3d-compiler: vkd3d-shader/hlsl.c:452: hlsl_init_deref_from_index_chain: Assertion `chain' failed.
because on the path that triggers the following error:
E5002: Wrong type for argument 1 of 'tex3D': expected 'sampler' or 'sampler3D', but got 'sampler2D'.
a NULL params.resource is passed to hlsl_new_resource_load() and
then to hlsl_init_deref_from_index_chain().
Since in SM1 all vector types use 4 register components, and since SM1
doesn't consider vectors of different dimx incompatible, it is necessary
to ensure that the semantic var is created with dimx=4, and to add a
cast node.
The use of the hlsl_semantic.reported_duplicated_output_next_index field
allows reporting multiple overlapping indexes, such as in the following
vertex shader:
void main(out float1x3 x : OVERLAP0, out float1x3 y : OVERLAP1)
{
x = float3(1.0, 2.0, 3.2);
y = float3(5.0, 6.0, 5.0);
}
apple.hlsl:1:41: E5013: Output semantic "OVERLAP1" is used multiple times.
apple.hlsl:1:13: First use of "OVERLAP1" is here.
apple.hlsl:1:41: E5013: Output semantic "OVERLAP2" is used multiple times.
apple.hlsl:1:13: First use of "OVERLAP2" is here.
While at the same time avoiding reporting overlaps more than once for
large arrays:
struct apple
{
float2 p : sv_position;
};
void main(out apple aps[4])
{
}
apple.hlsl:3:8: E5013: Output semantic "sv_position0" is used multiple times.
apple.hlsl:3:8: First use of "sv_position0" is here.

It is illegal to match a SPIR-V multisampled resource to a Vulkan resource which
is not multisampled. Vulkan considers a resource to be multisampled if its
sample count is greater than 1 (and SPIR-V does not care about the sample count).
This fixes validation errors in the case where the sample count does actually
match the resource. In order to provide correct behaviour when there is a
mismatch, or when the sample count is missing, we will need yet another
additional interface. In the absence of that it seems best to provide a best
guess.
This fixes a validation error with the not-yet-committed merge request 135, when
the d3d11 runner is run through Wine with the Vulkan backend.
