VMThrowable.java (getStackTrace): Pass trace as-is to modified lookup().

Browse Source 
* java/lang/VMThrowable.java (getStackTrace): Pass trace as-is to
	modified lookup().
	* gnu/gcj/runtime/NameFinder.java (lookup): Change to take in a
	StackTraceElement directly.
	(newElement): New native helper method to create StackTraceElement
	bypassing Java access control.
	(createStackTraceElement): Use newElement() instead of directly
	calling StackTraceElement's constructor.
	* gnu/gcj/runtime/natNameFinder.cc (newElement): New method.
