[perl #77496] tied gets scalars and globs confused

Make pp_tied use the SvFAKE flag to distinguish between tied scalars
and tied handles. This is now possible as of change 2acc3314.

This fixes the problem of tied($scalar) ignoring the tie if the last
thing returned or assigned happened to be a glob.
