SI-6179 mirrors now work with value classes

mirrors now carry a class tag of the receiver, so that they can detect
value classes being reflected upon and adjust accordingly (e.g. allow
Int_+ for ints, but disallow it for Integers).

Surprisingly enough derived value classes (SIP-15 guys that inherit from AnyVal)
have been working all along, so no modification were required to fix them.
