[RFA] Remove command_line_handler_continuation.

[Vladimir Prus <vladimir@codesourcery.com>]

With my previous patch to move all bpstat_do_actions calls into
event handler, all that command_line_handler_continuation does
is to print timings, if those are enabled. However, those timings
don't make much sense. Timings are good for debugging GDB performance,
and in case of command_line_handler_continuation, the times will report
the time when the application run.

So, this patch removes that continuation. OK?

- Volodya

	* top.c (command_line_handler_continuation): Remove.
	(execute_command): Do not install the above.
