target/hppa: Store full iaoq_f and page offset of iaoq_b in TB
In preparation for CF_PCREL. store the iaoq_f in 3 parts: high
bits in cs_base, middle bits in pc, and low bits in priv.
For iaoq_b, set a bit for either of space or page differing,
else the page offset.
Install iaq entries before goto_tb. The change to not record
the full direct branch difference in TB means that we have to
store at least iaoq_b before goto_tb. But since a later change
to enable CF_PCREL will require both iaoq_f and iaoq_b to be
updated before goto_tb, go ahead and update both fields now.
