Bill Wendling bc07a8900c Use pointers to the MCAsmInfo and MCRegInfo. 
Someone may want to do something crazy, like replace these objects if they
change or something.

No functionality change intended.

Richard Sandiford 14a4449589 [SystemZ] Rename PSW to CC 
Addresses a review comment from Ulrich Weigand.  No functional change intended.

I'm not sure whether the old TODO that this patch touches still holds,
but that's something we'd get to when adding a targetted scheduling
description.

Rafael Espindola b08d2c2db0 Remove addFrameMove. 
Now that we have good testing, remove addFrameMove and create cfi
instructions directly.

Rafael Espindola 1b09836bc3 Change getFrameMoves to return a const reference. 
To add a frame now there is a dedicated addFrameMove which also takes
care of constructing the move itself.

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.
