* [JVM_IR] Limit inner class attributes to types in class file
Inner class attributes should only be recorded for types that
are materialized in the result class file. In particular, we
should not emit inner classes attributes for types that appear
only in fake overrides. We do map these types to track the
fake overrides for JVM signature clashes but they are not
materialized in the class file.
^KT-56104 Fixed
* [JVM_IR] Consistently pass around materialized boolean in mapType.
In details, this commit changes the following:
- it converts FIR when without branches to empty IR block without when
- it doesn't drop empty else branches in when anymore
- Make the implementations very similar, to fix KT-54833 where the
companion object case was forgotten for kotlinProperty.
- Optimize both functions to look up the function/property by name
first, to cover the most probable case when the JVM name of a
declaration is equal to its Kotlin name. This fixes KT-55937.

in startCoroutineUninterceptedOrReturn. Otherwise, the coroutine will
not be interceptable later.
Add a test, which checks, that intercepted continuation is released.

Previously, a function reference that used generic parameters from its
outer scope was lowered into a top-level non-generic subclass of
`FunctionN`, with `FunctionN` type arguments referencing type parameters
not present in the scope anymore. This sometimes resulted in generating
malformed mangled names.
From now on the generated subclass of `FunctionN` is generic. The needed
type arguments are passed upon instantiation, when the relevant generic
parameters are present in the scope.
function enter -> default 1 -> default 2 -> rest of function

This probably has no effect (in non-stupid code, at least), but it makes
graph construction more architecturally correct (now value parameters'
subgraphs get attached to a node).
Interpretation: a graph A is a subgraph of B if information available at
nodes of A depends on the paths taken in B. For example, local classes
are subgraphs of a graph in which they are declared, and members of
those classes are subgraphs of the local class itself - because these
members can reference captured values.
Consequences:
* if graph G is a subgraph of node N, then G is a subgraph of N's
owner;
* `ControlFlowAnalysisDiagnosticComponent` will only visit root graphs;
* `graph.traverse` will ignore subgraph boundaries, as if all subgraphs
are inlined into one huge root graph;
* if a control flow checker needs information from a declaration to
which a graph is attached, it must look at subgraphs explicitly.
For example, consider the `callsInPlace` checker. When a function
has a `callsInPlace` contract and a local declaration, the checker must
visit that local declaration to ensure it does not capture the allegedly
called-in-place argument - hence `graph.traverse` will look at the
nodes. However, the local declaration can also be a function with its
own `callsInPlace` contracts, so the checker should also run for it in
isolation. If that sounds quadratic, that's because unfortunately it is.
