After this change SAM adapters are being resolved in the same group
as members, thus their overload resolution happens simultaneously.
But in the case of overload resolution ambiguity try to filter out all
synthetic members and run the process again.
See the issue and new test for clarification

1) for all cases of misusing of JsModule report on JsNonModule as well
2) report about non-top-level declarations with JsModule/JsNonModule
3) report about JsModule/JsNonModule declarations inside file marked with JsModule/JsNonModule
4) report about usages of declarations not marked with both JsModule and JsNonModule from UMD module
'a<T>::foo' is reserved if 'a' is a simple name and can be resolved as an expression
(this can be extended to 'a.b.c<T>::foo' case, although that is rather hard to implement using PSI).
'a?::foo' is reserved if 'a' can be resolved as an expression.
For each platform declaration, there must be at least one impl declaration in
the module with the compatible signature; similarly, for each impl declaration,
there must be at least one platform declaration with the compatible signature.
Note that currently the presence of the 'impl' modifier is not checked yet.
Also, the sad fact is that if you have platform and impl declarations which are
not compatible, you get two errors: on the platform delcaration and on the impl
declaration. This needs to be addressed as well
Because PackageViewDescriptor may consist of several package fragments from
different modules (see LazyPackageViewDescriptorImpl#fragments), we now filter
out fragments from irrelevant modules before rendering them into the .txt
E.g. 'impl typealias Foo<A, B> = Bar<A, B>' is allowed; everything else
(variance, changing order of parameters, etc.) is pretty much disallowed.
This is done for simplicity: otherwise matching the platform/impl class scopes
would be not so straightforward
Do not report "unused parameter" for parameters of platform declarations. Do
not allow platform class constructors to have val/var parameters or have an
explicit delegation call to another constructor. Do not allow platform classes
to have 'init' blocks.
Also suppress the "supertype not initialized" error for platform classes: the
supertype should be initialized in the impl class
Also add a new capability for ModuleDescriptor, which is used to obtain the
platform in the multi-platform scenario in tests.
Suppress the following errors for platform functions: "function has no body"
and "nothing to inline". Also do not report redeclaration between platform and
non-platform functions because this is the case when the common +
platform-specific code are analyzed together.
Note that some diagnostics reported in tests are not yet implemented in this
commit, they appear in subsequent commits
1. Substitution variance (sv) is a substitution composition of type alias argument variance (av)
and corresponding expanding type argument variance (ev):
sv =
| av == ev -> av
| av == INVARIANT -> ev
| ev == INVARIANT -> av
| else -> (variance conflict error; av)
2. Resulting variance (rv) is a type argument composition of sv and type parameter variance (pv):
rv =
| sv == tv => INVARIANT
| sv == INVARIANT => INVARIANT
| tv == INVARIANT => sv
| else -> (variance conflict error; sv)
