[PATCH 03/10] for_each_eh_label callbacks take an rtx_code_label

[David Malcolm]

gcc/
        * except.c (for_each_eh_label): Within param "callback",
        strengthen param from rtx to rtx_code_label *.  Strengthen local
        "lab" from rtx to rtx_code_label *.  Remove redundant check on
        LABEL_P (lab), since this is known from the type rtx_code_label *.
        * except.h (for_each_eh_label): Within param "callback",
        strengthen param from rtx to rtx_code_label *.
        * reload1.c (set_initial_eh_label_offset): Strengthen param
        "label" from rtx to rtx_code_label *.
