Description
Maybe I'm missing something, but it seems invoking getClass does unnecessary boxing when applied to AnyVal values.

To summarize -
1.getClass returns the int primitive class, but actually does some boxing when looking at the bytecode. I'm not sure why this would be necessary.
1.asInstanceOf[Int with Tag].getClass returns the boxed java.lang.Integer class, even though removing the .getClass returns a primitive int value.
Because of this magic boxing performed in the bytecode, it makes it hard to inspect things at runtime to figure out if we're really dealing with a primitive or boxed value (particularly needed in test suites). Maybe there's a better way to get around that (welcoming suggestions), however, the superfluous boxing seems like something that should be removed.
