Rename usesCustomDAGSchedInserter to usesCustomInserter, and update a
...
bunch of associated comments, because it doesn't have anything to do
with DAGs or scheduling. This is another step in decoupling MachineInstr
emitting from scheduling.

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.
