[PATCH] warn-access: Fix up warning_at arguments

[Jakub Jelinek]

Hi!

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.

Bootstrapped/regtested on x86_64-linux and i686-linux, ok for trunk?

	* 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.
