Drew Paroski 84b9d9a3a2 Separate resources from objects, part 1 
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).
