  Log Message:
  -----------
  [lld/mac] Implement -umbrella

I think this is an old way for doing what is done with
-reexport_library these days, but it's e.g. still used in libunwind's
build (the opensource.apple.com one, not the llvm one).

  Log Message:
  -----------
  [lld/mac] Implement -final_output

This is one of two flags clang passes to the linker when giving calling
clang with multiple -arch flags.

I think it'd make sense to also use finalOutput instead of outputFile
in CodeSignatureSection() and when replacing @executable_path, but
ld64 doesn't do that, so I'll at least put those in separate commits.
