[PATCH v2 0/4] MR577: hlsl: Improve condition type validation.
-- v2: tests: Add tests for valid conditional types. vkd3d-shader/hlsl: Validate that condition expressions are numeric. vkd3d-shader/hlsl: Validate the condition data type for loops as well. vkd3d-shader/hlsl: Copy some missing fields in hlsl_type_clone(). https://gitlab.winehq.org/wine/vkd3d/-/merge_requests/577
