* libjava/prims.cc: Some old cleanups. The collector now

	handles test for out of memory.
	* libjava/prims.cc, libjava/gcj/javaprims.h:
	(_Jv_AllocObjectNoInitNoFinalizer, _Jv_AllocObjectNoFinalizer):
	New functions for finalizer-free allocation.
	(jvmpi_notify_alloc): Became separate function.
	* libjava/java/lang/Object.h, libjava/include/jvm.h: Adjust for
	revised vtable layout on IA64.  With TARGET_VTABLE_USES_DESCRIPTORS,
	there is only one extra descriptor.
