While there make getOption return a const reference so we don't have to put it
on the stack when calling methods on it. No functionality change.

It could even be made non-virtual if it weren't for bad compiler
warnings.
This demonstrates that ArgList objects aren't destroyed polymorphically
and possibly that they aren't even used polymorphically. If that's the
case, it might be possible to refactor the two ArgList types more
separately and simplify the Arg ownership model. *continues
experimenting*

This might be able to be simplified further by using Arg as a value type
in a linked list (to maintain pointer validity), but here's something
simple to start with.

This broke clang's crash-report.c test, and I haven't been able to
figure it out yet.
This reverts commit r186319.

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.

This is in preparation for switching the clang driver over to using LLVM's
Option library. Richard Smith introduced most of these changes to the clang
driver in r167638.

Most of these are updating the new R600 target and fixing up a few
regressions that have creeped in since the last time I sorted the
includes.
