Add /Zc:sizedDealloc- to work around VS 2015 bug

VS 2015's support for VC++ 14 sized deallocs causes __global_delete
to be exported from many object files, causing obscure and hard to
track linker errors.

The best workaround, as suggested here:

https://connect.microsoft.com/VisualStudio/feedback/details/1379741/-global-delete-function-is-inconsistently-generated

Is to use /Zc:sizedDealloc- to disable the new C++14 feature support
that is triggering this behavior change.
