[Mesa-dev] nir: find_msb vs clz

While working on the NIR to DXIL conversion code for D3D12, I've noticed that we're not exactly doing the best we could here. First some background: NIR currently has a few instructions that does kinda the same: 1. nir_op_ufind_msb: Finds the index of the most significant bit, counting from the
