Input and output types are crucial for type variable fixation order and
analysis of postponed arguments (callable references, lambdas).
Specifically, if there is non-fixed type variable inside input types of
a callable reference, then we'll postpone resolution for such callable
reference.
Initial example with the expected type `KMutableProperty1<*, F>` caused
problems because input types were computed incorrectly (while there
aren't input types here)

It's needed to estimate the count of steps for type approximation algorithm.
After the estimated count of steps, we consider such type recursive and this
algorithm returns some default value
#KT-28598 Fixed
{ 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
Fixes #KT-28334 for NI
I've put `isIncompatibleEnums` to TypeIntersector because I placed
all of its usages after all of the TypeIntersector::isIntersectionEmpty ones
^KT-28225 Fixed
Extract Java-specific code into module 'frontend.java' and use already
existing JavaAnnotationArgument facilities to determine the default
parameter value in an actual Java annotation class.
Annotation arguments are not yet supported because to create an instance
of AnnotationValue, we need a descriptor, which is not available at this
point.

Before this commit, we compared property visibility with constructor
visibility only, which is incorrect. Now we compare property visibility
also with class visibility
#KT-19613 Fixed
Otherwise, top-level function with the name 'equals' and suitable
signature will be (erroneously) treated as true 'equals' invocation,
leading to further exception (see EA-126602)
Idea is to intersect similar smartcasts on similar properties coming
from *different* instances (something like
'this.x == null && other.x == null' ).
It checks that we distinguish subjects of such smartcasts properly.
Currently behavior is undesired, see KT-27260
Avoid name clashes in cases such as
inline class Login(val login: String)
inline class Password(val password: String)
fun validate(login: Login) { ... }
fun validate(password: Password) { ... }
The design is to use `suspend fun` instead of coercion, just as suspend
lambdas.
However, this syntax is not supported in the parser. But this is not a
problem, since the coercion lead to internal compiler error.
As a workaround everybody uses suspend lambdas.
