35dda8a53c [SystemZ] Use SystemZCallingConv.td to define callee-saved registers 
Just a clean-up.  No behavioral change intended.

514756983e [SystemZ] Rename 32-bit GPR registers 
I'm about to add support for high-word operations, so it seemed better
for the low-word registers to have names like R0L rather than R0W.
No behavioral change intended.

1d09d56fe1 [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.
