[MLIR]`-remove-dead-values` triggers Assertion Failure `results.size() == 1 && "expected a single result type"'

[xisang0]

Test on commit: 6548b63
steps to reproduce:

mlir-opt test.mlir --remove-dead-values

test case:

module {
  llvm.func @mlirAsyncRuntimeAddRef(!llvm.ptr, i64) attributes {sym_visibility = "private"}
  llvm.func @mlirAsyncRuntimeDropRef(!llvm.ptr, i64) attributes {sym_visibility = "private"}
}

crash trace:

mlir-opt: /home/workdir/llvm-project-19/mlir/lib/Dialect/LLVMIR/IR/LLVMTypes.cpp:235: LLVMFunctionType mlir::LLVM::LLVMFunctionType::clone(TypeRange, TypeRange) const: Assertion `results.size() == 1 && "expected a single result type"' failed.
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace.
