Functions annotated with `__fastcall` or `__attribute__((__fastcall__))` or `__attribute__((__swiftcall__))` may contain SEH handlers even on Win64. This matches the behaviour of cl which allows for `__try`/`__except` inside a `__fastcall` function. This was detected while trying to self-host clang on Windows ARM64. llvm-svn: 348337
