## What changes were proposed in this pull request? This PR fixes all the instances which was fixed in the previous PR. To make sure, I manually debugged and also checked the Scala source. `length` in [LinearSeqOptimized.scala#L49-L57](https://github.com/scala/scala/blob/2.11.x/src/library/scala/collection/LinearSeqOptimized.scala#L49-L57) is O(n). Also, `size` calls `length` via [SeqLike.scala#L106](https://github.com/scala/scala/blob/2.11.x/src/library/scala/collection/SeqLike.scala#L106). For debugging, I have created these as below: ```scala ArrayBuffer(1, 2, 3) Array(1, 2, 3) List(1, 2, 3) Seq(1, 2, 3) ``` and then called `size` and `length` for each to debug. ## How was this patch tested? I ran the bash as below on Mac ```bash find . -name *.scala -type f -exec grep -il "while (.*\\.length)" {} \; | grep "src/main" find . -name *.scala -type f -exec grep -il "while (.*\\.size)" {} \; | grep "src/main" ``` and then checked each.
