Tobias Tebbi cee2f772c7 [build] disable C++ optimization for mksnapshot code. 
By disabling C++ optimizations for code that's only run in mksnapshot,
that is, CSA and Torque-generated code, we can save compile time.
I observed up to 2x improvements of compile time for some files,
while the mksnapshot time did not increase significantly.

    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/*
