Identify data exports during split_link

Generates proper .def files that include "DATA" so that non-functions are
correctly exported.

However, for split_link because the "other" side won't import them properly
(__declspec(dllimport) is required) split_link notes them, and errors out.

This also adds support for linking individual objs out of libs so that some
_constants.cc and _switches.cc files can easily be linked into both DLLs.
