  [DAG] Constant fold + canonicalize integer binops before SimplifyVBinOp call

SimplifyVBinOp still has a FoldConstantArithmetic call, which now it isn't vector specific we should be able to remove (once fp binops are tidied up); but we can at least clean up the integer opcodes to perform the basic constant/undef handling in common code first.
