[clang+lld] Pass -platform_version args to ld64.lld

[int3]

Summary

Fix regression where we aren't passing -platform_version to new ld64.lld after D95204: [lld-macho] Switch default to new Darwin backend.

Most of the changes were originally in D95204, but I backed them out due to
test failures on builds which have CLANG_DEFAULT_LINKER=lld. The tests are
properly updated in this diff.

If I understand this right, the right patch description should be "fix regression where we didn't pass -platform_version to new ld64.lld after D95204", right? It's good to fix this :)

The test changes look like http://reviews.llvm.org/rGa9eaf8435d9204f5d71a08cfd7c574e92d434871 so I think they're right :)
