Igor Sheludko 139fe2db1c [ic] Implement TransitionArray lookup in CSA. 
Drive-by cleanup: remove megamorphic stub cache lookup support from generic property
store code. This lookup is no longer necessary because
1) fast stores to existing properties get all the information from the map,
2) transitioning store targets are taken directly from the transition array,
so in both cases there's no point in doing a store handler lookup.

    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/*
