* unwind-dw2-fde.c (get_cie_encoding): Replaced _Unwind_Word with
_uleb128_t and _Unwind_SWord with _sleb128_t.
* unwind-dw2.c (extract_cie_info, execute_stack_op, execute_cfa_program,
uw_frame_state_for, uw_update_context_1): Likewise.
* unwind-c.c (parse_lsda_header, PERSONALITY_FUNCTION): Likewise.
* unwind-pe.h (read_uleb128, read_sleb128,
read_encoded_value_with_base): Likewise.
* unwind-generic.h: Define _sleb128_t and _uleb128_t types.
