Re: [PATCH v2 03/10] tcg: Use one-insn-per-tb accelerator property in curr_cflags()

As mentioned against the cover, this is a very hot path.
We should try for something less expensive. Perhaps as simple as
return cpu->tcg_cflags | tcg_cflags_global;
where cpu->tcg_cflags is updated with cpu->singlestep_enabled.
