I think this solution is far more complex than it should be. We could
change it so that if an adrp is out of range for any address in the
code cache (rather than simply from the current PC) the multi-
instruction form is emitted. That way we won't need far_adrp() and we
won't need all the extra patching code.
Even if we went for all the extra patching, far_adrp() is still
unnecessary: all we have to do is make sure that the target is
reachable from the code cache and do adrp; nop or adrp as necessary.
