For more context see https://discourse.llvm.org/t/psa-ir-output-changing-from-debug-intrinsics-to-debug-records/79578

This change: https://github.com/llvm/llvm-project/commit/6a45fce90937f1c8671e609c4218818ce4491329
broke this test: https://github.com/llvm/llvm-project/blob/main/llvm/test/tools/dxil-dis/debug-info.ll
in our pipeline: https://github.com/llvm/llvm-project/actions/workflows/hlsl-matrix.yaml

LLVM is transitioning off of the llvm.dbg.value debug intrinsic in favor of the `#dbg_declare(..) format. see https://github.com/llvm/llvm-project/pull/133917/files

dxil-dis does not understand the new format and so work needs to be planned out to support this transition in https://github.com/microsoft/DirectXShaderCompiler

For now the fix is to XFAIL this test to unblock the pipeline.
