remove function casts from target.c 

This cleans up target.c to avoid function casts.

2014-02-19  Tom Tromey  <tromey@redhat.com>

	* target.c (complete_target_initialization): Remove casts.  Use
	return_zero_has_execution.
	(return_zero): Add "ignore" argument.
	(return_zero_has_execution): New function.
	(init_dummy_target): Remove casts.  Use
	return_zero_has_execution.
