Truffle CallNode API

[Christian Humer]

Hi folks,

I just updated the Truffle Inlining API with a more robust solution (will
get pushed to openjdk this night).
I removed the old API namely the following interfaces InlinableCallSite and
InlinedCallSite.
As a replacement for those classes you should now use a new class CallNode.
This class is already a Node and can directly be used as such inside of an
polymorphic function inline cache.
For further information on how to use it please see SLDirectDispatchNode
and the javadoc in the CallNode class.

Feel free to ask further questions.

Thanks.
