Basic handling of CIE version 4 in dwarf reading CIE looks like it's been emitted by clang since ~May 2015 [1]. This means that we didn't have any CFI because this parse aborted, which meant that all stack walks reverted to stack scanning. Allow expected values for address size and segment descriptor size through so that dump_syms can generate at least somewhat reasonable data.
