reproduce with: `mlir-opt -test-func-erase-arg a.mlir`
a.mlir:
```mlir
module {
llvm.func @f(%arg0: f32 {test.erase_this_arg}) {
%0 = "emitc.constant"() <{value = 1 : index}> {test.erase_this_arg} : () -> index
"test.return"(%0) : (index) -> ()
}
llvm.func @_mlir_ciface_f(%arg0: f32 {test.erase_this_arg}) attributes {test.side_effect = true} {
llvm.call @f(%arg0) : (f32) -> ()
llvm.return
}
}
```
