Not sure about this Russian chip but in the case of Transmeta and Nvidia Denver (and to a lesser degree, Intel x86 µops), writing the "native" code directly is not beneficial in any way.
The whole point is that the JIT compiler running in the CPU can make dynamic optimizations that's somewhat similar in nature to doing branch prediction and other optimizations modern CPUs do.
The native code executed by these CPUs is a poor target for static compilation. Without runtime data about which branches are taken, which memory locations are touched, etc, it is not possible to generate code that outperforms the built-in JIT or can compete with more traditional CPUs.
And besides, the JIT frontend in these chips is rather cheap in terms of power and performance.
