Victor Costan 679c317efb Restore typed array serialization format. 
https://crrev.com/c/3297708 changed the serialization format for typed
arrays without bumping the format version. As a consequence, builds that
include that CL fail to deserialize typed arrays serialized by previous
V8 versions.

This CL reverts the serialization format change, and does minimal test
changes to reflect the revert. https://crbug.com/v8/12532 tracks
serializing typed array flags in a backwards-compatible manner.

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/*
