bmeurer 9ee47bbc09 [turbofan] No need to load the feedback vector on the JS graph level. 
Fix JSLoadGlobal/JSStoreGlobal, JSLoadNamed/JSStoreNamed and
JSLoadProperty/JSStoreProperty to take the current function closure
instead of the type feedback as input, and load the feedback vector
from the closure as required (in JSGenericLowering). There's still
JSLoadDynamic left to be done, and then we don't have any machine
operators in the initial JS graph left.

There'll be more refactoring on the JSGenericLowering in a follow-up
CL, which takes care of the current code duplication and also tries
to use the more efficient LoadIC/KeyedLoadIC instead of the current
LoadICInOptimizedCode/KeyedLoadICInOptimizedCode (and same for store
ICs) whenever possible.

    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/*
