Added ## method to Any as our scala hashCode me...
Added ## method to Any as our scala hashCode method which provides
consistent answers for primitive types. And I'm sure we're all tired of
new starrs, but it's hard to add a method to Any without one. This patch
only brings ## into existence, but nothing calls it yet.
// some true assertions
scala> assert(5.5f.## == 5.5f.hashCode)
scala> assert(5.0f.## != 5.0f.hashCode && 5.0f.## == 5L.##)
