[Bug middle-end/45705] [4.3/4.4/4.5/4.6 Regression] Useless store not optimized away

[rguenth at gcc dot gnu dot org]

Eventually predicated value-numbering will fix this as part of the
redundant store removal eliminate() performs.

A similar thing can be added to DOM, which already can do the predication.
I'll give that a quick try.
