tcg: Allow extra data to be attached to insn_start
With an eye toward having this data replace the gen_opc_* arrays that each target collects in order to enable restore_state_from_tb. Reviewed-by: Aurelien Jarno <aurelien@aurel32.net> Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Richard Henderson <rth@twiddle.net>
