Support Windows big-obj format
By default, an object file can hold up to 65,536
(2^16) addressable sections. This is the case no matter which target platform is specified. /bigobj increases that address capacity to 4,294,967,296
Most modules will never generate an .obj file that contains more than 65,536 sections. However, machine generated code, or code that makes heavy use of template libraries may require .obj files that can hold more sections.
