    c++: Update const_decl handling after r15-7259 [PR118673].

    Objective-C++ uses CONST_DECLs to hold constant string objects
    these should also be treated as mergable lvalues.

            PR c++/118673

    gcc/cp/ChangeLog:

            * tree.cc (lvalue_kind): Mark CONST_DECLs as mergable
            when they are also TREE_STATIC.
