Prior to this CL we regularly generated high counts of code dependencies, and installation was not the most efficient. This CL 1) implements early dependency deduplication and 2) simplifies the way dependencies are persisted on the heap through DependentCode. Re 1): we dedupe twice, once based on the CompilationDependency contents, and again once we know the final target object. Re 2): Instead of a linked list of weak fixed arrays per dependency group, store deps in a flat array together with a bitset of their dependency groups.

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/*
