re PR libgcj/1516 (Method.invoke won't accept boolean parameters)

	Fix for PR libgcj/1516:
	* java/lang/reflect/natMethod.cc (primitives): Remove void entry.
	Add boolean entry.
	(can_widen): Declared inline. Remove redundant checks for void
	arguments and char->short conversion. Add special case for boolean
	conversions.
	(ffi_type): Declared inline.
	(_Jv_CallAnyMethodA): Move unwrapping logic inside isPrimitive() block.
