Subject: [PATCH] 	Fix MI timings.

        * mi/mi-main.c (mi_print_timing_maybe): New.
        (captured_mi_execute_command): Simplify. Output timings to
        CLI commands, too.
        (mi_execute_async_cli_command): Do not print timings.
        * mi/mi-main.h (mi_print_timing_maybe): Declare.
        * mi/mi-interp.c (mi_on_normal_stop): Call mi_print_timing_maybe.
