[PATCH] D40394: [FuzzMutate] Don't create load as a new source if it doesn't match with the descriptor

When we look for pointer which matches the operand descriptor, we test it using undef constant. In some cases it is possible that constant matches, but the load from pointer doesn't. In this patch I explicitly create the load and remove it later if it doesn't match.
