[issue17611] Move unwinding of stack for "pseudo exceptions" from interpreter to compiler.

[Serhiy Storchaka]

The main problem was with the frame.f_lineno setter. I have finally solved it in PR 5006. It solves also the regression in the with statement mentioned in msg307577 (by just restoring the original SETUP_WITH), and some other minor issues which I forgot.

Tests for the frame.f_lineno setter are provided in issue32416. I want to backport these changes and add new tests in PR 5006 (which allows to catch more illegal jumps than the current code), thus a separate issue. PR 2827 and PR 4682 crash with these tests.

Additionally PR 5006 may fix several issues with stack size calculation. I'll add tests later if there are reproducers.
