LLVM bitcode is still architecture specific - for example, whether the code is 64 bit or 32 bit will result in different bitcode paths.

You may be interested to look further into Eclipse OMR, which is a generic VM used by IBM for many of their runtimes (including J9). The Testarossa JIT support landed last week, and although it doesn't support bitcode form directly there are optimisations that can be used to transform the static parts of the class from the dynamic parts, to facilitate loading. There is an IL for the JIT and interpreter use.

Thanks for the pointer!

I (and others) have noted that for more than a decade, it seems that Java would have been better off under IBM than under Sun/Oracle (SWT vs. Swing/AWT, jikes vs. javac, Jalapeno/JikesRVM vs. not much interesting research until Graal, etc.) It's really a shame IBM didn't buy up Sun's Java intellectual property at fire sale prices.
