[PATCH] d3d11: Support D3D11_FEATURE_D3D10_X_HARDWARE_OPTIONS in ID3D11Device CheckFeatureSupport

[Józef Kucia]

This patch is probably fine because I don't expect that we will expose
compute shaders in SM4 (at least initially).

This is not important but I would name it d3d10_hw_opts or d3d10_opts.

It should be "ComputeShaders_Plus_RawAndStructuredBuffers_Via_Shader_4_x".
Besides, the trace() message could more clear, e.g. "Compute shader
support via SM4".
