Richard Sandiford db39b4a212 [SystemZ] Fix caller-allocated save slot FIXME 
Get rid of some old code (and associated FIXME) for handling the
caller-allocated register save area.  No behavioural change intended.

Ulrich Weigand 5f613dfd1f [SystemZ] Add back end 
This adds the actual lib/Target/SystemZ target files necessary to
implement the SystemZ target.  Note that at this point, the target
cannot yet be built since the configure bits are missing.  Those
will be provided shortly by a follow-on patch.

This version of the patch incorporates feedback from reviews by
Chris Lattner and Anton Korobeynikov.  Thanks to all reviewers!

Patch by Richard Sandiford.
