On hppa, I think we should go with the hook that assumes there is no
speculative execution.
Nominally, there is branch prediction and speculative execution; but the
spectre test program
was not able to successfully access memory on my rp3440.
As far as I know, the details of speculative execution on PA-RISC are
not public. Jeff would know
