This is a cleanup patchset to change all young flag check functions to
return bool, as discussed with David in the previous thread[1]. Since
callers only care about whether the young flag was set, returning bool
makes the intention clearer. No functional changes intended.
Ran mm selftests on Arm64 and x86 machines, and no issues were found.
Note that I only CC'd the arch mailing lists to avoid disturbing too
many people.

I did compile and boot test on powerpc with various configs and overall
it looks good.
Really appreciate your help with testing!
