My later debugging patches need access to the origin PC which is held in
the TranslationBlock structure. Pass down the whole structure as it also
holds the information about the code start point.

---
v1
 - checkpatch fixes
v5
 - much simplified due to changes since last posting
v6
 - remove needless tweaking of gen_code_buf in tb_gen_code
