    Correctly handle forward DIE references in scanner

    The cooked index scanner has special code to handle forward DIE
    references.  However, a bug report lead to the discovery that this
    code does not work -- the "deferred_entry::spec_offset" field is
    written to but never used, i.e., the lookup is done using the wrong
    key.

    This patch fixes the bug and adds a regression test.

    The test in the bug itself used a thread_local variable, which
    provoked a failure at runtime.  This test instead uses "maint print
    objfiles" and then inspects to ensure that the entry in question has a
    parent.  This lets us avoid a clang dependency in the test.
