* target.h: Add TARGET_WAITKIND_LOADED and TARGET_WAITKIND_SPURIOUS.

Browse Source 
* target.c (store_waitstatus): Add CHILD_SPECIAL_WAITSTATUS hook.
	* infrun.c (wait_for_inferior): Replace SIGTRAP_STOP_AFTER_LOAD with
	code which looks for those two waitkinds.  Use switch statement.
	* config/rs6000/tm-rs6000.h: Replace SIGTRAP_STOP_AFTER_LOAD with
	CHILD_SPECIAL_WAITSTATUS.
