This is required for d3d10+, which has depth_clamp always enabled
regardless of depth_clip (in contrast to OpenGL, where enabling
depth_clamp disables depth_clip). There doesn't seem to be a GL
extension for it, but it will be used for lavapipe to implement
VK_EXT_depth_clip_enable.

Currently, drivers infer the line rasterization mode from the
multisampling and line_smooth rasterization state. This is always
correct for OpenGL, but is subtly incorrect for DirectX 9, 10 and
Vulkan (when VK_EXT_line_rasterization is supported).
So let's allow front-ends to choose freely between rectangle and
paralellogram rendering.
The reason why there's no added cap for this, is that the implicit
selection that drivers currently do will work just as well (or more
correclty, just as subtly wrong) as before. And there's nothing
reasonable the front-ends can do to get the correct behavior, so
there's really no fall-back code to write either.

This change adds a gallium D3D10 state tracker that works as a WDDM UMD
software driver, similar to Microsoft WARP, but using llvmpipe/softpipe.
The final deliverable is a d3d10sw.dll, which is similar to WARP's
d3d10warp.dll.
This has been used to run Microsoft Windows HCK wgf11* tests with
llvmpipe, and they were at one point passing 100%.
Known limitations:
- TGSI (no NIR)
- D3D10 only (no D3D11 support yet)
- no WINE integration (WINE doesn't implement WDDM DDI.)
For further details see:

v2: Drop the DXBC-based disassembly. Add missing break statements.
v3: Incorporate Jesse's feedback.
