Nico Weber 6880cc2ddb Make it possible to cross build linux->win in standalone v8 builds 
With this, you can add `target_os = ['win']` to your .gclient file,
re-run runhooks, and then:

    $ cat out/gnwin/args.gn
    target_os = "win"
    use_goma = true

    $ gn gen out/gnwin
    Done. Made 234 targets from 103 files in 311ms

    $ ninja -C out/gnwin d8 -j1000
    ninja: Entering directory `out/gnwin'
    [1051/1051] LINK d8.exe d8.exe.pdb

    $ file out/gnwin/d8.exe
    out/gnwin/d8.exe: PE32+ executable (console) x86-64, for MS Windows

cbruni asked for this in
https://bugs.chromium.org/p/chromium/issues/detail?id=1196278#c6
I thought I'd give it a try and went to my v8 standalone checkout, only
to find that that already had a local diff for this. So I guess someone
else must've asked for this a while ago, so might as well check this in :)

V8 JavaScript Engine

V8 is Google's open source JavaScript engine.

V8 implements ECMAScript as specified in ECMA-262.

V8 is written in C++ and is used in Google Chrome, the open source browser from Google.

V8 can run standalone, or can be embedded into any C++ application.

V8 Project page: https://v8.dev/docs

Getting the Code

Checkout depot tools, and run

    fetch v8

This will checkout V8 into the directory v8 and fetch all of its dependencies. To stay up to date, run

    git pull origin
    gclient sync

For fetching all branches, add the following into your remote configuration in .git/config:

    fetch = +refs/branch-heads/*:refs/remotes/branch-heads/*
    fetch = +refs/tags/*:refs/tags/*
