[SPARK-20280][CORE] FileStatusCache Weigher integer overflow
## What changes were proposed in this pull request?
Weigher.weigh needs to return Int but it is possible for an
Array[FileStatus] to have size > Int.maxValue. To avoid this, the size is
scaled down by a factor of 32. The maximumWeight of the cache is also scaled
down by the same factor.
## How was this patch tested?
New test in FileIndexSuite
