* dwarf2out.c (output_call_frame_info): For dw_cie_version
>= 4 add also address size and segment size fields into CIE
header.
* unwind-dw2.c (extract_cie_info): Handle CIE version 4, as
long as address size is the same as sizeof (void *) and
segment size is 0.
* unwind-dw2-fde.c (get_cie_encoding): Likewise. If
address size or segment size is unexpected, return DW_EH_PE_omit.
(classify_object_over_fdes): If get_cie_encoding returned
DW_EH_PE_omit, return -1.
(init_object): If classify_object_over_fdes returned -1,
pretend there were no FDEs at all.
