Here's another patch that chops the time to run kimwitu++ in the JIT effectively
in half again:

There are other minor improvements that can be made, but I think a 4x
improvement in bytecode loading speed is enough for now.  Note that these
changes should significantly reduce the time to link LLVM programs as well.
