When embedding mono in another application, it's not possible to enable --jitmap, since that option is only parsed by mono_main. Ideally, there would be a way to supply a callback instead of mono_emit_jit_tramp so that mono's JIT map could coexist with other maps generated by the host application. However, even the existing behavior would be useful (if it could be enabled through mono_jit_parse_options or an environmental variable).

On a related note, --profiler is also unavailable except via mono_main.
