Yes: you ought to be able to declare the functions with
GCC_JIT_FUNCTION_IMPORTED in the parent context to get a long-lived
gcc_jit_function * object, and then call them from child contexts.

I believe I did something like this when porting GNU Octave's JIT to
libgccjit.

I don't think there's an example of this in the docs yet (we probably
should have a tutorial showing the use of a parent context for shared
setup).
