Tuple.fromProduct doesn't handle Product0

Minimized code

scala> case class Foo()

scala> Tuple.fromProduct(Foo())
java.lang.AssertionError: assertion failed

  ... 27 elided

Expectation

Tuple.fromProduct(Foo()) should return EmptyTuple.

On this note: Why is it called EmptyTuple instead of Tuple0?
We have Function0, Product0 (at least I think we do) and EmptyTuple, which appears to be inconsistent naming-wise.

Solution

The match in scala.runtime.Tuples.fromProduct simply needs another branch, similar to the one already present in fromArray.
