[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.

Ban rematerializable instructions with side effects.
...
TableGen infers unmodeled side effects on instructions without a
pattern. Fix some instruction definitions where that was overlooked.
Also raise an error if a rematerializable instruction has unmodeled side
effects. That doen't make any sense.

Merge the SystemZ subreg_even32 SubRegIndex into subreg_32bit. The SubRegIndices
...
were overspecified when inheriting sub-subregisters, for instance:
R0Q:subreg_even32 = R0Q:subreg_32bit = R0Q:subreg_even:subreg_32bit.
This meant that composeSubRegIndices(subreg_even, subreg_32bit) was ambiguous.

Update SystemZ to use PSW following the way x86 uses EFLAGS. Besides
...
eliminating a use of MVT::Flag, this is needed for an upcoming CodeGen
change.
This unfortunately requires SystemZ to switch to the list-burr
scheduler, in order to handle the physreg defs properly, however
that's what LLVM has available at this time.
