The algorithm is:
1) Write java version of your helper with magics
2) Teach JIT to replace particular instruction with your Java method call
3) Ask JIT to inline the method.

Check jitrino/src/optimizer/helper_inliner.cpp code and try to trace how any
of exising helpers is inlined, for example write barrier or allocation
helper.
