Otherwise when tb_exit generates a jump beyond the pc-relative range,
tcg_out_goto() spans two/three instructions and we load the tb return
value from a wrong address. This is #ifdefed out currently because
we take care for the jumps to be local.
Problem spotted by Steffen Liebergeld.

Unfortunately this range is so narrow that I'm not sure if it makes more
sense to always use memory load to pc kind of branch instead.

Calling the clear cache syscall directly generates an illegal instruction

Data integrity is not important in qemu-img, so open the files with
cache=writeback. This fixes the performance regression seen with qemu-img
since revision 5485, and most particularly with the qcow2 format.

Should not give any performance penality given cpu_mmu_index() is

All archs use the same cpu_loop_exit, so move the prototype in a common

this arch anyway.
