This option enables LowerInvoke's obsolete SJLJ EH support, but the target used in this test (ARM Darwin) no longer uses the LowerInvoke pass, so the option has no effect here. This target currently uses the newer SjLjEHPrepare pass instead. This cleanup will help with removing "-enable-correct-eh-support".
