Compiling pos and run tests from TASTY

[nicolasstucki]

These are the tests that still fail from tasty. Several of these tests fail due to same issues (will classify them later). This list was added as tests in #3593 which allows easy reproduction of the issues.

We had a few regressions since I listed them first, #3693 will ensure this does not happen again.

This list is now maintained in dotty.tools.dotc.FromTastyTests. Will close the issue as it is too hard to keep in sync.
