    warn-access: Fix up warning_at arguments
    
    A warning regression fix I'm about to post warns (and breaks bootstrap due
    to that) on the following spot.  Seems it is a copy and paste from
    earlier code that mentions the %qD variable instead of talking about
    unnamed temporary.

            * gimple-ssa-warn-access.cc (pass_waccess::warn_invalid_pointer):
            Avoid passing var to warning_at when the format string doesn't
            refer to it.
