Beef up some dllexport tests.
Adds some dllexport tests to verify that:
- Variables in bss are exported appropriately
- Non-dllexport symbols aliased to dllexport symbols are not exported
- Symbols declared as dllexport but are not defined are not exported
We plan to enable dllimport/dllexport support for the PS4, and these
additional tests are for points we noticed in our internal testing.
Patch by Warren Ristow!
