This is required to be able to compile KGP and it's dependencies which
set LV to 1.4 when repo will use LV 1.9. This caused by the change how
enums are compiled (KT-48872).
There are cases when we have some indices in TypeRegistry left from
previous compilations, so registering new service may increase index
not by one
So such situation is possible:
First compilation (jvm project): register 20 different jvm services in
session + one from compiler plugin (with index 21)
Second compilation (common project): register only 10 common services in
session + one from compiler plugin (with index 21)
*numbers are imaginary
And in this situation increasing `ArrayMapImpl.data` size only one time
may not cover required index

Not fully initialized DeclarationDescriptor could leak to bindingTrace.
It is hard to detect the outcome of that kind of leakage due to
possibility to have not fully initialized instances if PCE happens in
the middle of publication and instance full initialization.

FunctionalTypeKind can be used in FE 1.0 too, so there is no need to
keep both classes. Also, removal of FunctionClassKind simplifies work
with FunctionalTypeKind in common code, like Analysis Api
Root cause:
Cached in ClassValue values are prohibited to reference any java.lang.Class or ClassValue instances as they are considered as strong roots that prevent Class and ClassValue garbage collection,
creating effectively unloadable cycle.
This problem is also known as JDK-8136353.
Actions taken:
* Extract anonymous ClassValue instance into a separate static class that does not capture anything implicitly
* Wrap cached values in ClassValue into SoftReference to avoid unloadable cycles

Resolver could be GCed if there is no any valid hard reference to it.
Some impl of PackageFragmentProvider (like DelegatingPackageFragmentProvider)
keep hard ref to resolver.
For the sake of investigation it is worth to know what kind of PFP is there.

It affected the changed test in the following way: "strict metadata
version semantics" is a flag which is written to the .kotlin_module file
between the version and the protobuf data, see `ModuleMapping:73`. But
flags are written only for Kotlin 1.4+, i.e. if `isKotlin1Dot4OrLater`
returns true. So in the test, the flag was not written, thus we did not
detect that the module actually has incompatible metadata, and thus
incorrectly did not report an error.
It also has an effect that version requirements for nested classes will
now be written correctly to protobuf with metadata version 2.0+.
Using `ReflectionProperties.lazy` is incorrect because it allows several
threads to observe different resulting values if they're computing it
simultaneously (unlike `lazy(PUBLICATION)`, which always returns the
value that "won the race").
In the case of property delegates, for example, if we're invoking
`isAccessible = true` and then `getDelegate()` concurrently, it might
happen that when some thread invokes `getDelegate()`, it gets the
underlying Field object which was written by another thread and which
has not yet been made accessible, leading to
IllegalPropertyDelegateAccessException.

- 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.

Otherwise, when adding a typealias to core/builtins, it leads to an
exception "JvmBuiltins instance has not been initialized properly". It
happens because we start computing typealias constructors even before
the compiler has been initialized properly.
Basically we're creating the container, and as a part of it, we're
computing default imports, and for that we need to get all top-level
classifiers from scopes imported by default, which includes typealiases.
Eager call to `getTypeAliasConstructors` here results in computing
constructors of the class descriptor on the RHS of the type alias, which
is not possible if that class is built-in, since the container has not
yet been created and thus `JvmBuiltIns` has not been initialized yet.
No tests added, and no issue is affected because, as mentioned above,
the problem is only reproducible if we add something to core/builtins.
With this flag we can distinguish enum classes that have `entries`
property in the compiled bytecode (see `LanguageFeature.EnumEntries`).
This is needed to be able to understand in the frontend whether
`entries` can be called for that class. For Native and JS, this is
currently not possible even if the feature is enabled, but the class
was compiled with disabled feature.

Avoid filling caches with keys that are definitely empty
(if it's cheap to compute that), to decrease the size of backing maps.
The strategy is pre-computing the sets of names that might be met.
NB: the size of the sets is way fewer than a size of all queried names.
Initially, it was added accidentally as part of e3f987459c
and missed all out processes.
Adding @SinceKotlin("1.7") after the annotation has already been
published before is not really a problem, because it only may be used
with an experimental `-Xcontext-receivers` flag, thus it doesn't have
to be a part of our regular backward compatibility routine.
