Hello!

I have pushed the initial implementation for defining and wiring in the 
new top interface types viz InlineObject and IdentityObject
on behalf of

(1) JBS issue: https://bugs.openjdk.java.net/browse/JDK-8237069 
(Introduce and wire-in the new top interfaces)
       HG change set: 
http://hg.openjdk.java.net/valhalla/valhalla/rev/57fcdeb4a5b2

and

(2) JBS issue: https://bugs.openjdk.java.net/browse/JDK-8237955 
(Identity types that have no declaration sites fail to be IdentityObjects)
     HG change set: 
http://hg.openjdk.java.net/valhalla/valhalla/rev/e2f1c4d5f39e

These are implementing behavior defined here: 
http://cr.openjdk.java.net/~briangoetz/valhalla/sov/02-object-model.html

A small number of tier1 tests are failing.

I have raised JDK-8237952: (Reflection API/tests behavior needs to be 
spelled out for injected top interfaces)
to handle the failures in

java/lang/annotation/TypeAnnotationReflection.java
java/lang/annotation/typeAnnotations/GetAnnotatedInterfaces.java
java/lang/reflect/Generics/TestC1.java
java/lang/reflect/Generics/TestC2.java

I have also raised the following other defects against VM, core-libs:

JDK-8237959 - Need special handling of jlO constructor
JDK-8237958 - VM should implicitly treat arrays as IdentityObjects

On my machine, I also see the following two tests fail:

compiler/valhalla/valuetypes/TestCallingConvention.java
serviceability/jvmti/RedefineClasses/TestRedefineCondy.java

I am having trouble with running the former as a single test (it fails 
with missing class file for Whitebox permission) and the latter test is 
perhaps best tackled by someone from serviceability area.

FYI,
Thanks
Srikanth
