5fef80c5aa change the LabelSDNode to be EHLabelSDNode and make it hold
an MCSymbol.  Make the EH_LABEL MachineInstr hold its label
with an MCSymbol instead of ID.  Fix a bug in MMI.cpp which
would return labels named "Label4" instead of "label4".

987770c05d Progress towards shepherding debug info through SelectionDAG.
No functional effect yet.  This is still evolving and should
not be viewed as final.

7acf9be6c4 move target-independent opcodes out of TargetInstrInfo
into TargetOpcodes.h.  #include the new TargetOpcodes.h
into MachineInstr.  Add new inline accessors (like isPHI())
to MachineInstr, and start using them throughout the 
codebase.

3d1f3f707f 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.

3393a4c997 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.

00c9f3e905 Mark dead physregdefs dead immediately. This helps MachineSink and
MachineLICM and other things which run before LiveVariables is run.

605f85e0e6 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.
