The creation of the section `dead after deoptimization` shown in the attachment [yield_after_deopt_failure.log](https://bugs.openjdk.org/secure/attachment/102602/yield_after_deopt_failure.log) is prevented by this.

It's not worth to execute all test cases with the new mode though. Instead `ContinuationCompiledFramesWithStackArgs_3c4` is always executed a 2nd time in this mode.
