        * dwarf2out.c (rtl_for_decl_init): If vector decl has CONSTRUCTOR
        initializer, use build_vector_from_ctor if possible to create
        VECTOR_CST out of it.  If vector initializer is not VECTOR_CST
        even after this, return NULL.

        * d++.dg/debug/const3.C: New test.
        * d++.dg/debug/const4.C: New test.
