I recently realized that the vector config is call-clobbered.
We need this reset as well in tcg_out_call_int(), 
OK.
and prepare_host_addr().

In prepare_host_addr, place the reset just after the two calls to 
new_ldst_label().

As slow path will also cal tcg_out_call_init, can we only reset after 
tcg_out_call_init?

Thanks,
