  -----------
  [clang] Do not merge traps in functions annotated optnone

This aligns the behaviour with that of disabling optimisations for the
translation unit entirely. Not merging the traps allows us to keep
separate debug information for each, improving the debugging experience
when finding the cause for a ubsan trap.
