SI-6482 preserve bounds on tparams of value class

Each test needs to have its own package because pos_all will try to
compile the whole valueclasses directory at once.

The remaining tests with "extends AnyVal" in tests/pending/pos are
related to separate compilation, except for:
- t6482.scala and t7022.scala which were fixed by
  scala/scala#1468 in scalac and seem to
  trigger a similar bug in FullParameterization
- strip-tvars-for-lubbasetypes.scala which was fixed by
  scala/scala#1758 in scalac
