In HHVM (and HPHPc before it) we've been piggybacking resources on the KindOfObject machinery. At the language level, resource is considered to be a different type than object, and there are a number of differences in behavior between objects and resources (ex. resources don't allow for dynamic properties, resources don't work with the clone operator, the "(object)" cast behaves differently for resources vs. objects, etc). Piggybacking resources on the KindOfObject machinery has some downsides. Code that deals with KindOfObject values often needs to check if the value is a resource and go down a different code path. This makes things harder to maintain and harder to keep parity with Zend. Also, these extra branches hurt performance a little, and they make it harder for the JIT to do a good job in some cases when its generating machine code that operates on objects. This diff prepares the code base for a new KindOfResource type by adding a new "Resource" smart pointer type (currently a typedef for the Object smart pointer type) and it updates the C++ code and the idl files appropriately. This diff is essentially a cosmetic change and should not impact run time behavior. In the next diff (part 2) we'll actually add a new KindOfResource type, detach ResourceData from the ObjectData inheritence hierarchy, and provide a real implementation for the Resource smart pointer type (instead of just aliasing the Object smart pointer type).
