----------------
If there are no further requests, I won't post another review for this, but the final patch will do away with these "isa" calls and replace them with dyn_cast calls and the corresponding getConstantOperandVal() calls will be replaced with getZExtValue() calls on the resulting ConstantSDNode's.
