change filter comparison type for samplers, update test name

[bob80905]

Previously, no filter was specified for the samplers that perform a comparison. So, the filter defaulted to D3D_FILTER_ANISOTROPIC. The filter type should be D3D_FILTER_COMPARISON_ANISOTROPIC instead.

Thanks! This fixes the issue I saw with the results from tex.SampleCmpLevelZero().

DirectXShaderCompiler/tools/clang/test/HLSL/ShaderOpArith.xml

Line 3698 in 9cd1f68

result[7*2 + ix%2] = tex.SampleCmpLevelZero(g_sampCmp, -0.5, (float)INDEXER(32, ix)) ? (float)INDEXER(32, ix) : 0.0;
