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.

3a38e5e3c4 Let AnalyzeNewNode take care of calling ExpungeNode.
This makes sure that all new nodes are expunged, not
just those the top node of a new subtree.

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.
