Now that the groundwork has been laid, enabling CF_PCREL within the
translator proper is a simple matter of updating copy_iaoq_entry
and install_iaq_entries.
We also need to modify the unwind info, since we no longer have
absolute addresses to install.
As expected, this reduces the runtime overhead of compilation when
running a Linux kernel with address space randomization enabled.

Install iaq entries before goto_tb. The change to not record
the full direct branch difference in TB means that we have to
