MLIR Program:
```mlir
module {
func.func @m(%arg0: memref<4x?x16xf16>, %arg1: index, %arg2: index, %arg3: index) -> () {
%5 = llvm.mlir.constant(3.000000e+00 : f16) : f16
%27 = vector.transfer_read %arg0[%arg1, %arg2, %arg3], %5 : memref<4x?x16xf16>, vector<8xf16>
return
}
}
```
Reproduce Command: `mlir-opt --test-emulate-narrow-int=memref-load-bitwidth=32 --cse a.mlir`
StackTrace:
```
