E.g. devirtualization: this requires knowing the Java type (not LLVM type)
of an object. But once you compile to LLVM, that information is lost.

If e.g. you're loading LLVM pre-compiled modules then you can never
do this optimization because you can't recover the Java type information
(which is front-end specific).
