[ELF] Fix finding locations in messages for undefined hidden symbols. Previously, when `--vs-diagnostics` was used, the linker printed something like hidden(undef.s): error: undefined hidden symbol: foo >>> referenced by undef.s:15 Differential Revision: https://reviews.llvm.org/D65499 llvm-svn: 367515

[ELF] For VS-style diagnostics, prefer printing full paths in the header. The filename part in the message header is used by Visual Studio to fill Error List so that a user can click on an item and jump to the mentioned location. If we use only the name of a source file and not the full path, Visual Studio might be unable to find the right file or, even worse, show a wrong one.
