[Bug middle-end/19721] New: [meta-bug] optimizations that CSE still catches

["steven at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

This is a meta bug for tracking what CSE still does and
other passes do not catch.  After some SPEC runs with CSE
disabled completely or with at least CSE path following
disabled, it seems that we are very close to the point
where cse.c can be cleaned up significantly.

Please hang any known missed-optimization bugs involving
cse.c from this meta-bug.
