Our currently default "Oracle" is the "AOT Oracle", aka. fullAOT+interp:

1. AOT compile a assembly with --aot=full,interp
2. execute runtime with --full-aot-interp.

I would like to introduce a Hash Oracle, in order to stress test the mixed mode transitions, we should have a mode that decides seemingly randomly, but in a deterministic fashion. This can be achieved by using a hash-function for a method and a seed, for example:

gboolean use_interp = (hash(method) ^ seed) / (double)INT_MAX > 0.5
