This is the JDK code which works on top of ricochet frames.

These frames were put into the JVM last week, also under bug 6939861 in the 
hotspot repository.

It fixes a large number of bugs pertaining to argument conversions, argument 
count limitations, and the filtering, collection, and spreading of arguments 
and return values.

Several new unit tests are added.  All of them pass on x86 (32 and 64 bit).  
SPARC and ARM ports are in progress but are not required for common code to be 
pushed.

The unit tests also pass (up to known pre-existing failures) when 
-XX:-UseRicochetFrames is given to the JVM.  The old JDK code is preserved, 
which supports down-rev versions of the JVM (no ricochet frames).  This old 
code is marked clearly for future deletion and cleanup.
