These helpers don't seem very helpful. Isn't it better to use `switch` on the
value returned by `GetRegisterInfo().GetRegisterSetFromRegisterIndex(reg)`?

+ if (error.Fail())
----------------
To be honest, it seems counterproductive to restore the duplication that I've
removed before. Is there any real advantage to having two methods here, and
calling them separately from inside the `if` instead of calling
`ReadRegisterSet(set)` before the `if`?
