Andreas Kling 6bdb81ad87 Kernel: Split VMObject into two classes: Anonymous- and InodeVMObject
InodeVMObject is a VMObject with an underlying Inode in the filesystem.
AnonymousVMObject has no Inode.

I'm happy that InodeVMObject::inode() can now return Inode& instead of
VMObject::inode() return Inode*. :^)
