[PATCH v4 0/2] Implement pahole-like 'ptype /o' option (and do some code reorg)

[Sergio Durigan Junior]

Changes from v3:

- Simplified need_access_label_p.

- Fixed a few typos.

- Improved comments on c_print_type_struct_field_offset and
  c_print_type_union_field_offset.

- Removed unused variable.

- Added @smallexample to docs.


Eli had approved the documentation bits for the previous patch, but
since this one had an addition (the inclusion of an @smallexample
showing the output of 'ptype /o'), I believe it'd be good if he could
review it again.

Thanks,
