The first time a block is translated it will exit back to the main loop.
After the next block is translated the previous TB is patched via
tb_add_jump which calls tb_set_jmp_target to set the target TB.
Computed jumps or jumps that cross page boundaries are generally handled
via the lookup_tb_ptr helper function.
