Jeremy Dubreil d20c8a0222 [infer][backend] Add functions to separate the cases when the subtyping relation can be proven from the case where the no subtyping relation can be proven. ... Summary: The two concepts are not negation of each other. The type environment created by the different frontends is not guaranteed to contain a full view of the type hierarchy. In this case, there can be holes preventing Infer to prove that `t <: t'` if the type definition between `t` and `t'` is missing. There are now two functions: # `is_known_subtype` when the subtyping relation can be proven # `is_known_not_subtype` when it can be proven that there is no subtyping relation between two types This diff is intended to make no functional changes but to add functionality to detect cast error angelically, i.e. assuming that the program is probably fine where there is not enough information to prove the cast error.
