Split torque generated files for faster build

By using different namespace, generated code split into different files.

By this CL, build time of torque_generated_initializers is improved from 80 seconds to 40 seconds on Z840 Linux measured by following command:

# Remove generated code to re-compile all generated files.
~/v8/v8$ rm -rf out/x64.release/gen/
# GOMA_STORE_ONLY=true disables goma's backend cache.
~/v8/v8$ time GOMA_STORE_ONLY=true autoninja -C out/x64.release/ torque_generated_initializers

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/*
