[SPARK-17460][SQL]check if statistics.sizeInBytes >=0 in canBroadcast
## What changes were proposed in this pull request?
1. In SparkStrategies.canBroadcast, I will add the check
plan.statistics.sizeInBytes >= 0
2. In LocalRelations.statistics, when calculate the statistics, I will
change the size to BigInt so it won't overflow.
## How was this patch tested?
I will add a test case to make sure the statistics.sizeInBytes won't
overflow.
