In the HLSL case, it is possible to do this detection entirely based on declared signatures (it doesn't have a dependency on code generation like the GLSL case does). I've added test cases for the two main ways that a shader can become sample rate: 1. Qualify a fragment input with `sample` 2. Accept an input with the `SV_SampleIndex` semantic In each case I nested the input inside a `struct` to try to match common HLSL idiom, and to make sure that we handle the nested case. This code is *not* robust against shaders that declare such an input and then never use it, but that is to be expected given the goals for Slang. * Fixup: add missing test output files
