So you only really need to preserve convenience variables whose types
are builtin types, and don't go away when symbol tables are reloaded. 
Wouldn't it be simpler just to have clear_internalvars only clear
variables whose types belong to objfiles?

Or you could define a hook that runs a user-defined command when the
architecture changes.  Then your script could define a command that
sets up your variables, and have GDB run that command when the
architecture is known.  We'd have to think about the best time to run
the hook, but I'm sure something reasonable could be worked out.
