Please note that enum values are slightly different from V8 upstream, i.e PPC_POWER10 instead of kPPCPower10.
We also have SIMD enabled upstream which will not be backported here.

@richardlau is test-crypto-timing-safe-equal-benchmarks flaky on s390? as my changes are ppc specific.

@miladfarca The test has been failing a lot recently on s390x: #38226
It’s not clear as to what has changed to make the test fail and whether or not there is an underlying defect.

Thanks for the link. Yes some other tests seem to be flaky too i.e inspector-cli/test-inspector-cli-address failed on AIX and inspector-cli/test-inspector-cli-pid on ppc on the previous runs.

Should this target master instead of v16.x-staging?

@aduh95 There is already a PR open to update V8 on master, I've request a cherry pick: #38273

@richardlau Would you please help with landing this as well?
Also is there a way to only re-run the AIX test? Failure shouldn't be related to this PR.
