When SimplifySetCC was moved to the DAGCombiner, it was never removed from
...
SelectionDAG and it has since bitrotted. Remove the copy from SelectionDAG.
Next, remove the constant folding piece of DAGCombiner::SimplifySetCC into
a new FoldSetCC method which can be used by getNode() and SimplifySetCC.
This fixes obscure bugs.

Merging ISD::LOAD and ISD::LOADX. Added LoadSDNode to represent load nodes.
...
Chain and address ptr remains as operands. SrcValue, extending mode, extending
VT (or rather loaded VT before extension) are now instance variables of
LoadSDNode.
Introduce load / store addressing modes to represent pre- and post-indexed
load and store. Also added an additional operand offset that is only used in
post-indexed mode (i.e. base ptr += offset after load/store).
Added alignment info (not yet used) and isVolatile fields.

Fix for PR929. The PHI nodes were being gone through for each instruction

in a successor block for every block...resulting in some O(N^k) algorithm
