[Bug tree-optimization/23939] New: DOM has dead code, VALUE_HANDLEs are not created during DOM

[pinskia at gcc dot gnu dot org]

While looking into PR 23049, I noticed that DOM checks the tree code of expressions making sure that 
they are not VALUE_HANDLE.  I looked and the only place which creates a VH is in tree-vn.c and none of 
those are called from DOM.
