bryleun 0d24a0fcfe S390: Fixed s390 simulation check for underflow in subtraction. 
Clang optimizes away CheckOverflowForIntSub at any opt
level (includes -O1, -O2, -O3) into a false statement,
resulting in incorrect values being returned. As the C++
standard considers overflows to be undefined behaviour,
this is technically correct as compilers can assume that
overflows never occur, but problematic in our case (where
overflows do occur, and a specific result is expected).

This change replaces the original check with a call to a
function that is optimized in a manner that returns correct output.

    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/*
