[PATCH] d3dcompiler_43/tests: Added trigonometric function tests to HLSL test suite

[Travis Athougies]

Changes from last version:

- Both sin and cosine tests are now run simultaneously
- Used newer probing infrastructure and got rid of compute_shader_linear9
- Adapted to current coding conventions
