    middle-end/108086 - reduce operand scanner use from inliner
    
    The following avoids a redundant second operand scan on all stmts
    during inlining which shows with PR108086.
    
            PR middle-end/108086
            * tree-inline.cc (copy_edges_for_bb): Do not update all
            stmts again.
