pc_offset = 0x7ffff800 will fail:
lo = 0xfffffffffffff800
hi = 0x0000000080000000
but hi will be interpreted as negative by pcaddu12i.
This is the same problem I pointed out with tcg_out_call, but with
different constants.
Hmm, I think I'll have to look into this, but not now (it's again 3 am
here)... I'll try to come up with something tomorrow.
