Tests

838+ tests across three categories:

• Unit tests — device, resources, views, states, formats, shader compilation, draw and compute pipelines, SM3 translator
• Golden tests — pixel-exact comparison against reference images for D3D11 and D3D9 rendering paths
• Perf tests — draw and compute benchmarks
