@richardlau Similar to #38509, I don't think I will be able to land this on my own either. |

Yes, only members of the backporters and/or release team can land on the staging branches. I'll land this if the CI's currently in progress pass. |

Please note that enum values are slightly different from V8 upstream, i.e
PPC_POWER10instead ofkPPCPower10.Power 9 is also added to some of the features within the ppc assembler, this is to make adding P10 consistent and is not part of the original CL on V8.
We have SIMD enabled upstream which will not be backported here.
