When NVidia adopted Transmeta's technology to target ARM instructions with their Project Denver they added a facility to just run native code for bits that weren't hot spots.
https://en.wikipedia.org/wiki/Project_Denver : "Project Denver was originally intended to support both ARM and x86 code using code morphing technology from Transmeta, but was changed to the ARMv8-A 64-bit instruction set because Nvidia could not obtain a license to Intel's patents"
Even though I'm not sure what you mean by "native", this not exactly my understanding. AFAICT, Denver added a hardware Arm instruction decoder. This greatly helps with the first part of the JIT and especially accelerates the interpreter.
