    debug/107058 - gracefully handle unexpected DIE contexts

    While the bug is persisting that LTO streaming picks up a CONST_DECL
    from an attribute argument on a VAR_DECL which with -fdebug-type-section
    refers to a DIE in a type unit we can handle this gracefully, at least
    with -fno-checking.  Do so.  The C++ frontend nevetheless should resolve
    the CONST_DECL attribute argument to a constant.

            PR debug/107058
            * dwarf2out.cc (dwarf2out_die_ref_for_decl): Gracefully
            handle unexpected but bogus DIE contexts when not checking
            enabled.

            * c-c++-common/pr107058.c: New testcase.=
