Default to delambdafy:method and backend:GenBCode

Switch the defaults of `-Ydelambdafy` and `-Ybackend`.

Rewrite t6288b-jump-position test - no more icode

Don't crash GenBCode beyond JVM code size limits
A similar patch is in GenASM, see 3fa2c97

Fix check files for GenBCode / delambdafy:method defaults

Force copy propagation test to ASM, see SI-9364

Force inline-ex-handlers test to GenASM, see SI-9364

Move t6613 test to pending - still broken in GenBCode
Adding a `flags` file with `-Ybackend:GenASM` doesn't seem to have
the desired effect.
SI-6613 is re-opened.

Force a few tests to GenASM, see SI-9364
