    this will allow the compiler to cache and reuse the result, meaning we
    no longer have to take care not to load it more than once for the sake
    of archs where the load may be expensive.
    
    depends on commit 1c84c999 for
    correctness, since otherwise the compiler could hoist loads during
    stage 3 of dynamic linking before the initial thread-pointer setup.
