[NI] Implement various optimizations for incorporation algorithm

Mostly, these optimisations are picked from the old inference.
 Also, remove exponential complexity for flexible types in approximation,
 note that more correct fix for this would be to introduce new types
 that corresponds just to platform types to avoid nullability problems,
 but due to complexity it will be done later
