I encountered a crash while using MLIR. The reproducer is the input program below:
```llvm
"builtin.module"() ({
"func.func"() ({
"gpu.barrier"() : () -> ()
"func.return"() : () -> ()
}) {sym_name = "main", function_type = () -> (), arg_attrs = [], res_attrs = []} : () -> ()
}) {} : () -> ()
```
**Stack Trace**
```bash
mlir-opt: /llvm-project/mlir/lib/Conversion/FuncToLLVM/FuncToLLVM.cpp:386: FailureOr<LLVM::LLVMFuncOp> mlir::convertFuncOpToLLVMFuncOp(FunctionOpInterface, ConversionPatternRewriter &, const LLVMTypeConverter &, SymbolTableCollection *): Assertion `!resAttrDicts.empty() && "expected array to be non-empty"' failed.
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace and instructions to reproduce the bug.
