HLSL: handle clip and cull distance input builtin type conversion HLSL allows a range of types for clip and cull distances. There are three dimensions, including arrayness, vectorness, and semantic ID. SPIR-V requires clip and cull distance be a single array of floats in all cases. This code provides input side conversion between the SPIR-V form and the HLSL form. (Output conversion was added in PR #947 and #997). This PR extends HlslParseContext::assignClipCullDistance to cope with the input side conversion. Not as much changed as appears: there was also a lot of renaming to reflect the fact that the code now handles either direction. Currently, non-{frag,vert} stages are not handled, and are explicitly rejected. Fixes #1026. 2017-08-23 18:34:42 +00:00			`struct VS_OUTPUT {`
