I'm not sure the V8 version should be bumped, but definitely the v8_embedder_string in common.gypi needs to be bumped.

Bumping the V8 version is correct for 8.x (v8_embedder_string doesn't exist in this branch) https://github.com/nodejs/node/blob/master/doc/guides/maintaining-V8.md#backporting-to-abandoned-branches

Perhaps contribute the failing testcase to the V8 tests?

@MylesBorins, how long does this PR need before it can be merged into v8.x-staging? Could it make the v8.12.0 release on September 4th?
