ClassInfo needs a hasFinalizer field that is true iff the class or its ancestor has a non-empty finalizer.  This way, instead of conservatively flagging all GC-allocated objects with GC.BlkAttr.FINALIZE, only those that need to be finalized could be flagged.  On this benchmark (https://github.com/dsimcha/druntime/blob/master/gcBench/tree1.d) avoiding calling empty finalizers results in about a 20% speedup.

I'm marking this invalid even though it could be implemented because I realized it won't be useful.  rt_finalize needs to be called to finalize the monitor object if one exists, even if the class has no explicit finalizer.
