Turn Function.prototype.bind into a hydrogen stub optimized for the common case

This speeds up .bind by >10x as measured by
function f(a,b,c) {}

for (var i = 0; i < 10000000; i++) {
  f.bind(1); // or more arguments.

(Uses hydrogen-stubs rather than TF due to var-args + possible runtime fallback, which is still unsupported in TF.)

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/*


Please follow the instructions mentioned on the V8 wiki.
