[PATCH v4 0/1] MR321: vkd3d-shader/hlsl: Implement intrinsic tan.
Now that we can write HLSL intrinsics in HLSL, cleaning up missing functions becomes much easier. This commit also extends the trigonometry tests a little bit to make sure that tan works right. -- v4: vkd3d-shader/hlsl: Implement intrinsic tan. https://gitlab.winehq.org/wine/vkd3d/-/merge_requests/321

Why does it belong to this commit? Also, notice that if you don't add it to `Makefile.am` it won't be considered for running the tests.
