2c04b0da2b Use DenseSet rather than SmallPtrSet for the alive set. Using SmallPtrSet 
with a huge "size" parameter is actually quite inefficient.

have different alignment by creating a stack slot with the max
alignment of source and target type.

349db1738d instead of aborting on shifts of i1, just implicitly fold them. 
The dag combiner can produce a shift of i1 when folding icmp i1's.

4406604047 Split ISD::LABEL into ISD::DBG_LABEL and ISD::EH_LABEL, eliminating 
the need for a flavor operand, and add a new SDNode subclass,
LabelSDNode, for use with them to eliminate the need for a label id
operand.

Change instruction selection to let these label nodes through
unmodified instead of creating copies of them. Teach the MachineInstr
emitter how to emit a MachineInstr directly from an ISD label node.

This avoids the need for allocating SDNodes for the label id and
flavor value, as well as SDNodes for each of the post-isel label,
label id, and label flavor.
