Reviewers: Hannes Payer, Hablich,
Message:
Michael: This has the chance to bust a Canary because of bad interaction
with
the GC. We should time this CL so that it doesn't overlap with other risky
features being shipped (most likely after the branch point).
Hannes: PTAL.
Description:
Activate preserving of optimized code map accross GCs.
This enables --noflush-optimized-code-cache which allows preserving
entries in the optimized code map accross GCs. This only applies to
values being reachable through other paths.
