I triggered a `llc` assertion error on the following code
```llvm
source_filename = "operandbundle.ll"
define internal void @f(i32 %arg) {
entry:
call void @g() [ "foo"(i32 %arg) ]
ret void
}
declare void @g()
```

Steps to reproduce
```console
% llc test.ll -mtriple=x86_64
llc: /root/llvm-project/llvm/lib/CodeGen/SelectionDAG/SelectionDAGBuilder.cpp:9548: void llvm::SelectionDAGBuilder::visitCall(const llvm::CallInst&): Assertion `!I.hasOperandBundlesOtherThan( {LLVMContext::OB_deopt, LLVMContext::OB_funclet, LLVMContext::OB_cfguardtarget, LLVMContext::OB_preallocated, LLVMContext::OB_clang_arc_attachedcall, LLVMContext::OB_kcfi, LLVMContext::OB_convergencectrl}) && "Cannot lower calls with arbitrary operand bundles!"' failed.
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace.
