Reid Kleckner 72b819b8ee [InstCombine] Salvage debug info during initial DCE ...

InstCombine salvages debug info for every instruction it erases from its
worklist, but it wasn't doing it during its initial DCE when populating
its worklist. This fixes that.

This should help improve availability of 'this' in optimized debug info
when casts are necessary.
