- compute a FunctionCaller instance for getter and setter so that "call" only
delegates to that FunctionCaller's "call", in the same way it's done in
KFunctionImpl
- use RuntimeTypeMapper.mapPropertySignature to get the exact origin and
signature of a property and its accessors. This makes unwrapFakeOverride call
unnecessary and also fixes some cases like private Java fields
- temporarily drop custom range checks, will be re-added soon
To better emphasize the fact that all returned properties require an instance
of the class they are declared in. Another issue was that
'Some::class.extensionProperties' was sometimes incorrectly perceived as
"get all extension properties available on the class Some"
Get rid of all classes except kotlin.reflect.KFunction, which will be used to
represent all kinds of simple functions.
Lots of changes to test data are related to the fact that KFunction is not an
extension function (as opposed to KMemberFunction and KExtensionFunction who
were) and so a member or an extension function reference now requires all
arguments be passed to it in the parentheses, including receivers. This is
probably temporary until we support calling any function both as a free
function and as an extension. In JS, functions and extension functions are not
interchangeable, so tests on this behavior are removed until this is supported
