Peter Collingbourne cd40bd0a32 hwasan: Move .note.hwasan.globals note to hwasan.module_ctor comdat. ...

As of D70146 lld GCs comdats as a group and no longer considers notes in
comdats to be GC roots, so we need to move the note to a comdat with a GC root
section (.init_array) in order to prevent lld from discarding the note.
