Pavel Kirpichenkov b045adf83a [NI] Report unsafe implicit invoke accordingly to OI 
There are several issues with unsafe desugaring for convention calls.
Proper fix is not implemented here (see design proposal KT-30872).
This commit only applies the old logic in the new inference.

simon.ogorodnik 34e6649d31 [FIR] Harden check of argument type properly 
Before this commit, nullable argument could match not null parameter.
Now we require also correct nullability that breaks some cases

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 c6712ff861 [NI] Correctly compute definitely not null type for intersection one 
{ T : Any? & Foo & Bar? }!! -> { T!! & Foo & Bar }

 Also, fix bug with loosing non-representative number type.
 For example, for type { Byte & SomeType } we lost type `Byte` because
 `getDefaultPrimitiveNumberType` returns null for it

Denis Zharkov b4bb92d136 Fix overload resolution ambiguity for types intersection 
There are two different forms of types intestion:
1. Type parameters with multiple bounds
2. Smart casts

The problem was that when member scope of type intersection contained
effective duplicates and that lead to overload resolution ambiguity in
strange cases like `x.hashCode()`

For first type we do effectively the same thing as when building member
scope for class extending several interfaces: group all descriptors by
both-way-overridability relation and then choose most-specific in each
group.

For smart casts we do basically the same thing but with special
treatments:
1. From all descriptors that _equal_ to most specific we choose
   the one that works without smartcast if possible (i.e. we choose first from candidates list)
2. If smart-cast value seems to be unstable we use only member scope
   of receiver type + all descriptors from smart cast possible types
   that has incompatible signature. If we'd include all of them and
   choose one as more specific, and it would lead to false
   SMART_CAST_IMPOSIBLE (see test unstableSmartCast.kt)

Denis Zharkov aad977d204 Properly check whether nullability of receiver argument fits to parameter's nullability
