[PATCH 0/1] MR183: vkd3d-shader/hlsl: Always specify resource on intrinsic_tex().

[Francisco Casas (＠fcasas)]

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().
