8274527: Minimal VM build fails after JDK-8273459

[asgibbons]

Second of 3 dependent backports for Base64 that are required to get the real bugfix cleanly integrated. The next one will be for the buffer overrun bugfix required for Base64 decoding to work properly.

Depends on PR 860, 861, and 862.

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
