That's probably true on a per-program basis.  I.e. for semi-hosting or userland
emulation, hard-coding litbase into the TB could make sense.

However, for full system emulation, with kernel and userland et al, I would 
expect that litbase would tend to be set per-application.  At which point it
would almost certainly be more efficient to read the value at runtime.
