    tree-optimization/124627 - inlining and elided debug stmts

    When we fixup a noreturn call during inlining we can end up eliding
    debug stmts, so we have to make sure to not re-instantiate SSA
    operands on those later when processing all debug stmts.

            PR tree-optimization/124627
            * tree-inline.cc (copy_debug_stmts): Only copy debug
            stmts that are still in the IL.
