ARM: prevent crash on ELF directives on COFF Certain directives are unsupported on Windows (some of which could/should be supported). We would not diagnose the use but rather crash during the emission as we try to access the Target Streamer. Add an assertion to prevent creating a NULL reference (which is not permitted under C++) as well as a test to ensure that we can diagnose the disabled directives. llvm-svn: 218014
