I wouldn't expect to find Java equivalents of the C++ abstraction
penalty tests, since Java doesn't have stack-allocated objects. (My
understanding is that we improve on these tests due to being able to
split up and register-ize stack-allocated objects...)
Right now I think the tree-ssa benefits to Java are more potential
than actual. In the future we hope to get array bounds check
elimination, elimination of redundant type checks, and perhaps
elimination of redundant class initialization.
