Summary: Fix two bugs in SelectionDAGBuilder::FindMergedConditions reported by Mikael Holmen. Handle non-canonicalized xor not operation correctly (was assuming operand 0 was always the non-constant operand) and check that the negated condition is also in the same block as the original and/or instruction (as is done for and/or operands already) before proceeding with optimization.
