Log:
    PR middle-end/47401
    * except.c (sjlj_assign_call_site_values): Move setting the
    crtl->uses_eh_lsda flag to ...
    (sjlj_mark_call_sites): ... here.
    (sjlj_emit_function_enter): Support NULL dispatch label.
    (sjlj_build_landing_pads): In a function with no landing pads
    that still has must-not-throw regions, generate code to register
    a personality function with empty LSDA.
