I didn't really have a reason for limiting this to arm64 and non-windows OS
other than I didn't want to do too many things in the initial patch. I don't
think it would be hard to do this on x86-64. For windows, it looks like we'll
have to emit the markers and the ARC calls before CodeGen (before WinEHPrepare)
is run, but I haven't thought it through.

The check for module flag was here because the initial version of this patch
added the attribute when the target wasn't arm64 (e.g., x86-64) too. I've
removed the check for now.
