Description
4734748 introduced the tagged stack interpreter (TaggedStackInterpreter) to find the source for some bugs back then.  Since it failed some JCK tests it was never used as default or even tested and so it started bit-rotting.  Recent JSR 292 changes didn't implement the tagged stack interpreter anymore and other ongoing porting for different platforms and features would need to implemented it too.  We decided to drop it.
