Blockers for the update to V8 8.0

[targos]

We've got quite a few things to fix this time!

• Failing test-inspector-multisession-ws
• Failing test-assert
• S390x fails to build
• FreeBSD fails to build
• SmartOS fails to build
• Windows fails to build (VS2019)
• Windows fails to build (VS2017)
• Broken debug build
• incomplete zlib.gyp
• V8 zlib target fails for cross-compilation
• Debug build not working without --experimental-enable-pointer-compression

@targos Does #130 (comment) mean that the "incomplete zlib.gyp" bullet point should be checked off?

[targos]

@bnoordhuis I suppose we can check it off because it's no longer a blocker, but I didn't implement the conditions to load optimized code depending on the platform.

Is this still being worked on? I would love to have the latest v8.

Yeap. We have just fixed build issue on vs2019. Still some work todo. See #127 (comment) for update.

@SFx2018 There is a checklist at the top of this PR :)

V8 had to make some changes to make building with zlib work again: https://chromium-review.googlesource.com/c/v8/node-ci/+/2037570

[SFx2018]

any ETA for release for nodejs?

[gengjiawen]
