[PATCH] D29585: [SCEV] Fix for PR31847: Assertion failed: (isLoopInvariant(Operands[i], L) && "SCEVAddRecExpr operand is not loop-invariant!")

Sometimes during folding loop invariants the resulting add recurrence may become non-invariant. This may lead to crash during next folding of recurrences expected to be invariants, which are not.
