Yes, it's bogus.  ctid is never passed as NULL.  It might point at
an "invalid" itempointer (one with ip_posid == 0).  Look at the only
call site.

This seems to indicate that clang is stupider than I would have hoped.
Isn't it capable of doing the same types of analysis that gcc does
when inlining?
