  "message": "[SPIRV] Add pattern for breaking down vector.bitcast (#14151)\n\nThe pattern added here is to handle bitcast ops that failed to unroll to\r\na supported vector size. For example, this can happen in cases like the\r\nfollowing after SPIRVVectorize\r\n\r\n```mlir\r\n  %64 \u003d arith.trunci %33 : vector\u003c4xi32\u003e to vector\u003c4xi8\u003e\r\n  %65 \u003d vector.insert_strided_slice %64, %63 {offsets \u003d [28], strides \u003d [1]} : vector\u003c4xi8\u003e into vector\u003c32xi8\u003e\r\n  %66 \u003d vector.extract_strided_slice %49 {offsets \u003d [0], sizes \u003d [16], strides \u003d [1]} : vector\u003c32xi8\u003e to vector\u003c16xi8\u003e\r\n  %67 \u003d vector.bitcast %66 : vector\u003c16xi8\u003e to vector\u003c4xi32\u003e\r\n```\r\n\r\nWhere the intermediate `vector\u003c32xi8\u003e` can\u0027t be broken down without\r\nfirst breaking down the bitcast.",
