Is it the same as v8/v8@035c305? If so, can you apply the upstream commit instead (git node v8 backport 035c305ce7761f51328b45f1bd83e26aef267c9d). See https://github.com/nodejs/node/blob/master/doc/guides/maintaining-V8.md#backporting-to-abandoned-branches for detailed instructions.

For history, we had to patch up v8/v8@035c305 for 14.x so that LTS Node.js could continue to build against the existing ICU versions #39068.

I think so, but I tried to maintain backwards compat with older ICU versions.

Made a version based on that in #39451 in case that's preferable.
