* 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. From-SVN: r48002
