Remove unused imports and other minor cleanups

 - Language imports are preceding other imports
 - Deleted empty file: InlineErasure
 - Removed some unused private[parallel] methods in
   scala/collection/parallel/package.scala

This removes hundreds of warnings when compiling with
"-Xlint -Ywarn-dead-code -Ywarn-unused -Ywarn-unused-import".
