Reid Kleckner 95695c8bb3 [Option] Store arg strings in a set backed by a BumpPtrAllocator
No functionality change.

This is preparing to move response file parsing into lib/Option so it
can be shared between clang and lld.  This change isn't just a
micro-optimization.  Clang's driver uses a std::set<std::string> to
unique arguments while parsing response files, so this matches that.
