The pointer auth options PR would also benefit from this - it currently has an ad hoc and restricted version of this as it needed to support strings produced by builtins, and predated @cor3ntin's string evaluation change so that was not even remotely an option at the time.

I would much rather have us use a single string evaluation routine rather than the current behavior, but that would block the options PR on this one.
