arm: Don't potentially overwrite input registers in add2, sub2.
According to malc TCG will often genereate an add2/sub2/mul2 with lowhalf of the output in the same register as high half of one of theinputs, so account for that.

Don't rely on ARM tcg_out_goto() generating just a single insn.
Otherwise when tb_exit generates a jump beyond the pc-relative range,tcg_out_goto() spans two/three instructions and we load the tb returnvalue from a wrong address. This is #ifdefed out currently because...
arm: Reserve code buffer in memory range reachable for pc-relative branch.
Unfortunately this range is so narrow that I'm not sure if it makes moresense to always use memory load to pc kind of branch instead.

Use libgcc __clear_cache to clean icache, when available.
Calling the clear cache syscall directly generates an illegal instructionon some (armv4) kernels.

Don't try to select on an invalid VNC socket when init fails.
Otherwise we get a segfault.
