Pavel Kirpichenkov 4a7b4d655c [NI] Fix completion for ILT when Nothing constraint is present 
Full completion should not be done if lower `Nothing`
is the only proper constraint when constraint with ILT type is present.
ILT will be selected as a resulting type and transformed into `Int`
without attention to possible restrictions from outer calls.

Pavel Kirpichenkov 78c9bbcc0d [NI] Soften restictions on using Nothing as proper constraint for full call completion 
Consider lower `Nothing` constraint non-proper only if there is a dependant not analyzed postponed atom.
Early completion to `Nothing` provides data flow info for smart casts.

Mikhail Zarechenskiy f702417655 [NI] Relax rules for call completion: require at least one constraint 
It's enough to have at least one good constraint.

 Note that the whole algorithm can be a bit more general:
 we could check also Out<T>, In<T> and verify that T has good only
 lower constraint or upper constraint, but there are questions for
 types like Inv<Out<T>>, where T should have lower and upper constraints

Mikhail Zarechenskiy bcc8802014 [NI] Avoid constraints from expected type for effectively empty system 
Expression will be checked against expected type later.

 Theoretically, this is not very good, but it aligns with the old
 inference, plus it helps avoiding multiple type mismatch diagnostics.

Mikhail Zarechenskiy c458393e2f [NI] Do not avoid trivial constraints if they aren't from upper bounds 
Since we skipped trivial constraint with `Any?` from parameter type of
 function `equals`, the compiler thought that there is no proper
 constraints (upper bounds do not matter here) and marked resolved
 call as a failed one, then diagnostic about missing equals was added

 Also, tune `TrivialConstraintTypeInferenceOracle` for `Any?`-like
 constraints

Dmitry Petrov ae929d0f08 Handle nested when with subject properly 
Hack: callee expression for when with subject variable is the subject
variable declaration. This solves the problem that all sub-calls in the
expression are implicitly considered to have a single common lexical
scope (and 'when (val x = ...)' introduces a new lexical scope, which
contains 'x').

Dmitry Petrov 758548603e Extra tests for when with val in subject 2018-06-20 14:06:34 +03:00
Dmitry Petrov 091b935c2d Introduce separate callee expression for when with subject variable 
'Subject.Error' is redundant.
'Subject.None' can be an object.
'Subject#dataFlowValue' can be a lateinit property.

TODO: fix
- parsing local extension properties in 'when' subject
- parsing destructuring declarations in 'when' subject
- non-completed calls in nested 'when' with subject variable
- non-completed calls for subject variable in 'in' pattern

Dmitry Savvinov 33f9576dd1 [NI] Turn off KnownTypeParameterSubstitutor for NI 
The main consequence of it is that TYPE_MISMATCH range for control
structures became wider.

Also, for extra safety, don't change behaviour of OI.
