Yes, this forces the `const char *` from GeneratedArgs to be converted into
`StringRef`, which does comparison via `::memcmp`.
If we decide comparing `StringRef`s is a better solution, I'd be inclined to
create a helper function or custom matcher that does the conversion to
`StringRef`. That way, we don't have to worry about doing the right thing in
test cases.
