tests/shader-runner: Run SM1 compilation in the shader runner, part 1.
Like the previous MRs, this has the objective of:
- Preparing the way for SM1-specific tests.
- Running SM1 compilation tests, even if we don't have a runner available to execute them (yet).
- Allowing different runners to run through the shader_test file several times, targeting different shader model ranges.
The current plan is:
- We won't separate compilation tests from execution tests as in !418 (closed).
- Instead of naming individual shader models in the shader_test files as in !434 (closed), we will keep working with the shader model ranges provided in the [require] directives.
- We will test SM1 compilation going through the shader_test file twice with the vulkan runner, one for SM1 models and other for SM4 models, and for now we will just give a "todo" for execution tests until they are implemented (@zfigura patches).
This first part only includes facilities to properly mark SM1-specific tests (as required by !458 (merged)) and some refactoring to better work with the idea of intersecting shader model ranges.
