Removed warnings

- Added `since` to deprecation statement
- Added unit to parameter list
- Removed usage of deprecated method polyType
- Replaced deprecated `debugwarn` with `devWarning`
- Changed switch statement to if else in order to remove a warning
- Switched implementation of `init` and `processOptions` to prevent
warning
- Replaced deprecated `Console.readLine` with `scala.io.StdIn.readLine`
- Replaced deprecated `startOrPoint` with `start`
- Replaced deprecated `tpe_=` with `setType`
- Replaced deprecated `typeCheck` with `typecheck`
- Replaced deprecated `CompilationUnit.warning` with `typer.context.warning`
- Replaced deprecated `scala.tools.nsc.util.ScalaClassLoader` with `scala.reflect.internal.util.ScalaClassLoader`
- Replaced deprecated `scala.tools.ListOfNil` with `scala.reflect.internal.util.ListOfNil`
- Replaced deprecated `scala.tools.utils.ScalaClassLoader` with `scala.reflect.internal.util.ScalaClassLoader`
- Replaced deprecated `emptyValDef` with `noSelfType`
- In `BoxesRunTime` removed unused method and commented out unused values. Did not delete to keep a reference to the values. If they are deleted people might wonder why `1` and `2` are not used.
- Replaced deprecated `scala.tools.nsc.util.AbstractFileClassLoader` with `scala.reflect.internal.util.AbstractFileClassLoader`
