[jdk17u-dev] RFR: 8273108: RunThese24H crashes with SEGV in markWord::displaced_mark_helper() after JDK-8268276

[Scott Gibbons]

Last of 3 dependent backports for Base64 that are required to get the real bugfix cleanly integrated.

Risk: I view the risk of this backport to be minimal. This code has been in use for many months with no bugs reported.

Testing: x86_64 build, affected tests, tier1

Thanks,
--Scott
