…tion `SimplifyClones` used to generate an invalid op: ``` error: 'memref.cast' op operand type 'memref<*xf32>' and result type 'memref<*xf32>' are cast incompatible %2 = bufferization.clone %1 : memref<*xf32> to memref<*xf32 ``` This commit fixes tests such as `mlir/test/Dialect/Bufferization/canonicalize.mlir` when verifying the IR after each pattern (llvm#74270).
