Rafael Espindola cda2911caa Optimize linkonce_odr unnamed_addr functions during LTO. 
Generalize the API so we can distinguish symbols that are needed just for a DSO
symbol table from those that are used from some native .o.

The symbols that are only wanted for the dso symbol table can be dropped if
llvm can prove every other dso has a copy (linkonce_odr) and the address is not
important (unnamed_addr).

Rafael Espindola efa02d53ff Fix option parsing in the gold plugin. 
This was broken when options were moved up in r191680. No test because this is
specific LLVMgold.so/libLTO.so.
