The hppa host code has been removed since 2013; this
should have been deleted at the same time.

* If stack grows up, then we will be placing successive

* reverse the order compared to how we would normally
* treat either big or little-endian. For those arguments
* that will wind up in registers, this still works for
* HPPA (the only current STACK_GROWSUP target) since the
* argument registers are *also* allocated in decreasing
* order. If another such target is added, this logic may
* have to get more complicated to differentiate between
* stack arguments and register arguments.
