`ManglerChecker` is a class that verifies that for each IR declaration
(except some, see its `needsChecking` property) its mangled name
(computed from IR) is the same as the mangled name computed from its
frontend representation — `DeclarationDescriptor` on K1 or
`FirDeclaration` on K2.
The way it does it is as follows.
On K1, `ManglerChecker` looks if the declaration has a true,
non-IR-based descriptor, it if it does, then it checks it
(see ManglerChecker.Companion#hasDescriptor).
On K2, since we don’t have any descriptors, `ManglerChecker` looks if
the declaration’s metadata property is `null` (because the corresponding
`FirDeclaration` is stored there). If it’s not, it checks it
(see ManglerChecker.Companion#hasMetadata).
The issue is that those two conditions are not equivalent.
When the Compose compiler plugin transforms an IR function, it copies
its `metadata` property (as it should, because `metadata` can contain
anything, not necessarily the frontend representation), but doesn't set
the descriptor. Because of that, on K1 that transformed function is
skipped in `ManglerChecker`, and on K2 it’s not.
The correct usage would be to properly distinguish which declarations
come from the FE as is, and which are transformed/synthesized,
and skip the latter. But it is unclear how to implement this.
For now, the easiest way to fix this on K2 is to not run ManglerChecker
at all.

Ensure that in IdSignatureBuilder hashId/hashIdAcc is only set
together with the description.
In 6142d75bb4 we implemented setting
descriptions when building signatures from descriptors, but forgot to
do the same for building signatures from IR, resulting in missing
descriptions in klibs.

After this change SymbolTable (and ReferenceSymbolTable) contains only
methods with IdSignatures. All descriptors-related methods are moved
into DescriptorSymbolTableExtension, which automatically delegates to
the SymbolTable if needed
At this moment there are cross-references between SymbolTable, because
descriptor API is still actively used across backends. So SymbolTable
is accessible in some place then descriptor extension will be accessible
too
DescriptorSymbolTableExtension is an implementation of abstract SymbolTableExtension
which allows to implement different kinds of storages, e.g. FIR based
(it probably will be needed for FIR2IR)
This field shall be used for storing a human-readable representation
of the declaration, that would be a mangled name for now.
This field is not yet serialized. Serialization will be implemented in
follow-up commits.
See KT-59486
According to
`FirNativeCodegenBoxTestGenerated.testNestedClassesInAnnotations`,
the annotation
`kotlin.internal.PlatformDependent` is
unresolved reference.

Normally during metadata compilation we use
`K2MetadataCompiler` and it serializes
metadata to klibs without generating IR.
Native shared compilation uses the K2Native
compiler, which generates klibs based on both
the fir and fir2ir information.
It would be nice to reuse `K2MetadataCompiler`
for native shared, but currently it has no
support for the commonizer, and also reads
the stdlib metadata from a jar instead of a
klib, and there's no simple idiomatic way
to pass the `distribution.klib` value down
to `KLibResolverHelper` (native compilation
has some commonized dependencies, and they
explicitly depend on `stdlib`, so we must
resolve it this way or strip it away to be
able to use the metadata jar instead). There
may be other issues, I only digged a bit.
Instead, this change modifies the K2Native
in such a way that it can generate klibs
with metadata without fir2ir info.
Note that this change does not fix KT-58139,
because KT-58139 fails due to performing the
constants evaluation directly during the
metadata serialization when the needed info
does (and, as I was told, should) not exist
(namely, valid property initializers).
^KT-58444 Fixed
- Mangled names of property accessors now include context receiver
types of the corresponding property when computed from FIR.
- Context receivers are now supported when computing mangled names
from IR
- IrBasedDescriptors now account for context receivers
^KT-57435 Fixed
Single-letter names were very confusing, especially in declarations like
```kotlin
private inline fun <
reified D : IrDeclaration,
reified ES : IrDelegatingSymbol<AS, D, *>,
reified AS : IrBindableSymbol<*, D>
> finalizeExpectActual(
expectSymbol: ES,
actualSymbol: IrSymbol,
noinline actualizer: (e: D, a: D) -> Unit
)
```
Both explicitly specified and default argument expressions are considered.
In case an argument expression is considered as 'unlinked' the whole annotation
is removed from the declaration. An appropriate compiler warning logged for each
such case.
