PR 463053

My register stealing is a little over-agressive: I'm technically
being a little unsafe. Even if a register is dead on the normal
path, if a fault can occur before the register is written to, we
should restore its value in the fault handler. Pretty
pathological so for now we ignore it, given that we have larger
problems and we need the speed.
