Specifically, the report the following 4 errors.

* NON_VARARG_SPREAD

Jinseong Jeon e72ddbcbfe FIR checker: differentiate UNSAFE_CALL from INAPPLICABLE_CANDIDATE 
To do so, inside the root cause of inapplicable candidate errors,
we will record expected/actual type of receiver, if any.
That will help identifying inapplicable calls on nullable receiver.

Dmitriy Novozhilov e6b5cb5216 [TD] Update diagnostics test data due to new test runners 
Update includes:
- Changing syntax of `OI/`NI` tags from `<!NI;TAG!>` to `<!TAG{NI}!>`
- Fix some incorrect directives
- Change order of diagnostics in some places
- Remove ignored diagnostics from FIR test data (previously `DIAGNOSTICS` didn't work)
- Update FIR dumps in some places and add `FIR_IDENTICAL` if needed
- Replace all JAVAC_SKIP with SKIP_JAVAC directive

Dmitriy Novozhilov f283f2db43 [FIR] Improve diagnostic reporting & don't use error symbol for candidate if possible 
Also introduce few new diagnostics:
- NONE_APPLICABLE more many inapplicable candidates
- HIDDEN for visible candidates

Ilya Chernikov 6356807997 Reapply "Only create descriptors for candidates with lambda args" 
#KT-36247 fixed
A lot of testdata changed because significanly less (error) descriptors
are created for unresolved types, so diagnostics became different.

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 848640253a Revert "[NI] Disable capturing/approximation type in TypeSubstitutor with enabled NI" 
This reverts commit f20ec3e0a6.
 2019-05-29 01:31:28 +03:00
Dmitriy Novozhilov f20ec3e0a6 [NI] Disable capturing/approximation type in TypeSubstitutor with enabled NI 
There is added a new service named `SubstitutingScopeProvider`, that
  provides factory that creates captured types and approximator for them.
  In OI they are the same as before commit, for NI they are empty, because
  that approximation interferes with NI algorithm

That service is injected into function descriptors and property descriptors
  and used for creating `SubstitutingScope` with correct services

Also there is changed time when we approximate captured types in NI
  (after all call checkers)

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.

Dmitry Savvinov 33f9576dd1 [NI] Turn off KnownTypeParameterSubstitutor for NI

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