Don't mark registers dead here when processing nodes with MVT::Flag
...
results. This works around a problem affecting targets which rely on
MVT::Flag to handle physical register defs.

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.

MachineLICM and other things which run before LiveVariables is run.

Create a new InstrEmitter class for translating SelectionDAG nodes
...
into MachineInstrs. This is mostly just moving the code from
ScheduleDAGSDNodesEmit.cpp into a new class. This decouples MachineInstr
emitting from scheduling.
