Peter Wu ba0da850a8 [Object] Deduplicate long archive member names
Summary:
Import libraries as created by llvm-dlltool always use the same archive
member name for every object file (namely, the DLL library name). Ensure
that long names are not repeatedly stored in the string table.

BSD-THIN: Only the gnu format has a thin mode.
If an archive has an object with no symbols, the linker and some other
tools on some versions of Solaris will abort operations if there is no
symbol table. Create such an object, put it into an archive, and check to
see that there is an empty symbol table.
