Alexey Kozyatinskiy df6cf50bcd Reland "[runtime] introduced instrance type for each context type" 
This is a reland of 6da438fda1

Original change's description:
> [runtime] introduced instrance type for each context type
> 
> Each context type get own instance type:
> - we can make CSA checks more strict in couple places,
> - it is requires step for advanced evaluation without side effects.
