Splitting Matt's larger patch set:

> 1  accel/tcg: fold the dynamic cflags into CPUState::tcg_cflags

>    curr_cflags() recomputed three unlikely tests on every one of the run's
>    8.4 billion dispatches, from state that changes only when gdb enables
>    single-step, when one-insn-per-tb is toggled, or when the log mask
>    moves. Fold each into tcg_cflags where it changes.          -5.15%

Changes in v6:
  - Use update_guest_debug in system mode, rather than a tcg-specific hack
    in cpu_single_step.  This would also be required for split-accel, if
    and when that project gets regoing.

    Unfortunately, cpus_get_accel() can't be used in user mode, so
    fix things with an ifdef.

  - Hide other cflags updates behind tcg_enabled(), so that even if
    tcg is built in, we don't use it when using virtualization.
    This also means we don't need stubs, because tcg_enabled() will
    reduce to constant false with --disable-tcg.
