re PR libgcj/11951 (natMethod.cc (_Jv_CallAnyMethodA) should clear ffi_result before ffi_call)

	PR libgcj/11951:
	* java/lang/reflect/natMethod.cc (_Jv_CallAnyMethodA): Returns
	void.  Throw VirtualMachineError if ffi fails.  Initialize return
	value.  Added is_jni_call argument; only wrap exception if not a
	JNI call.  Use descriptive message if operation not supported.
	(_Jv_GetTypesFromSignature): Use declaring class' loader to find
	array class.
	* include/jvm.h (_Jv_CallAnyMethodA): Updated declaration.
	* jni.cc (_Jv_JNI_CallAnyMethodV): Updated for new form of
	_Jv_CallAnyMethodA.
	(_Jv_JNI_CallAnyMethodA): Likewise.
	(_Jv_JNI_CallAnyVoidMethodV): Likewise.
	(_Jv_JNI_CallAnyVoidMethodA): Likewise.
