[Bug middle-end/33349] Redundant zero-extension of registers

[steven at gcc dot gnu dot org]

This would be fixed if someone would fix the Sign Extension Elimination pass
(yes, it also handles zero extensions).  But that pass is probably broken
beyond repair at this point, and likely needs a rewrite instead of just a fix.
