I am working with a Java JIT compiler, particularly Jikes, and I was wondering what kinds of optimizations are available from this kind of compiler? I don't have any experience with these kinds of compilers, but do they do loop-unrolling and register renaming, or completely different methods?

Probably. I can't think of any reason they wouldn't be available, though it depends greatly on how the JIT is implemented; I know nothing about Jikes. (I bet the developers would know.)
