Build without thread-safe statics with VC++ 2015
For consistently with other platforms, and to avoid the overhead, build
with /Zc:threadSafeInit- to disable thread-safe statics on VC++ 2015.
VC++ 2013 did not support thread safe statics so this merely maintains
existing behavior across the transition.
This saves ~54 thousand bytes of file size in chrome*.dll.
