When testing different linkers, it's sometimes useful to run the tests with `SWIFT_DRIVER_TEST_OPTIONS=" -use-ld=<linker>"`. If we do this, it will break a handful of tests because they expect the compiler driver to choose an appropriate linker automatically. To avoid having these fail, detect when someone has done this, and set a new feature, `linker_overridden`, then mark the tests in question with `UNSUPPORTED: linker_overridden`. rdar://123504095
