- rename KTopLevelProperty to KTopLevelVariable
- create KTopLevelExtensionProperty, a subclass of KExtensionProperty
- create KTopLevelProperty, a superclass of KTopLevelVariable and
KTopLevelExtensionProperty. (In the future, it will have a container of type
KPackage.)
Metadata for KFunction classes is now longer serialized along with built-in
classes. This effectively means that it's no longer possible to find KFunction
classes via dependency on built-ins. There should be a kotlin-runtime library
in the specified classpath for reflection types to be resolvable.
A lot of tests were moved and changed, because tests on callable references
require stdlib in classpath from now on
