Previously, we applied type arguments as is when converting type alias
constructor calls to IR.
Now, we map them using the expansion of the type alias.
#KT-59743 Fixed
This allows us to properly complete array literals arguments of
annotation calls fixing several false-negative type mismatch errors
as well as enabling the inference of generic type arguments.

This is important for IR lowerings like PolymorphicSignatureLowering
which are very sensitive about the correct types of expressions and
placement of coercions to Unit (KT-59218).
A boolean parameter to `insertImplicitCasts` is not the best solution to
ensure that coercion to Unit is added. The best solution would be to fix
the TODO and generate coercion to the block's type for the last
statement. But that will affect many other places and will need to be
done separately => KT-59781.
Code in IrInterpreter is uncommented to fix the FIR test
`compiler/testData/ir/interpreter/exceptions/tryFinally.kt`; otherwise
evaluation of the function `returnTryFinally` there crashes with
"NoSuchElementException: ArrayDeque is empty". No idea why this test
didn't fail for K1 though, since the created IR is exactly the same.
For some unknown reason this breaks WASM backend with K2, but not with
K1 => KT-59800.
Before this change, it could happen that `when` of type Unit has a
branch whose type is not Unit. This can lead to problems in IR
lowerings, for example PolymorphicSignatureLowering which is very
reliant on the correct types of expressions and placement of coercions
to Unit (KT-59218).
Code in `ReplaceNumberToCharCallSitesLowering` relies on `Number.toChar`
being declared in IR as non-abstract. Otherwise the
`resolveFakeOverride` call there doesn't work, and the lowering can't
rewrite the call to `toInt().toChar()`, and we end up with a call to the
missing method `Number.toChar` in the bytecode.
#KT-57217 Fixed
In this commit we have a lot of change in test data. This was caused
by the way where we evaluate constants. We split constant evaluation
into two distinct parts: only necessary evaluations for `fir2ir`
(like const val and annotations) and optimizations for lowering.
Now we don't do all constant evaluation on `fir2ir`, but IR
dump is executed after this phase, so test data changed.
#KT-58923
This commit fixes the receiver of these method in FIR2IR code
by removing a particular hack.
However, as the consequence of it 2 black box tests become broken in K2.
The reason is KT-54952 which is not yet fixed

Before this fix, changes that were made to the arguments list by calling
argumentList.transformArguments() were overriden by replaceArgumentList.
This fixes reverses the order in which these calls are made.
This also aligns the logic between the completion of qualified accesses
and delegated constructor calls.
#KT-59102 Fixed
Generating IR declarations for use-site substitution overrides leads
to IR that is different from K1 as well as problems in signature
generation which relies on mangling. Use-site substitutions can contain
references to type parameters from the call-site which aren't handled
in mangling.
#KT-57022 Fixed
This only applies to JVM and fq-names in declaration references
in IR dumps.
This enables us to run more irText tests on platforms other than JVM
(see KT-58605).
This doesn't reduce the quality of tests, because the flags are still
printed for declarations themselves. We only omit them in references.
However, this makes the tests more compatible with non-JVM backends
(see KT-58605), because flags of referenced stdlib declarations may
differ among target platforms.
Previously, the semantic was more-or-less correct for most of the cases
but some corner one, like `sort` in MutableList didn't work properly.
Namely, `sort` should be marked there in a way to forbid to call it
everywhere beside super-calls.
Also, overriding it should be allowed.
Mostly, the logic was re-written to K2 model from K1-related
JvmBuiltInsCustomizer.

For type parameters of generic properties,
`DeclarationDescriptor#getContainingDeclaration` must return
the property descriptor instead of the accessor function descriptor.

Review: https://jetbrains.team/p/kt/reviews/9967
BTW this commit accidentaly and partially fixes KT-57553 for K2, because
of a cleaner K2 architecture. I will unify MUST_BE_INITIALIZED behaviour
in K1 and K2 in the next commits
- 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
The reason #1 for this feature is that we want to test IdSignatures
generated for declarations. Currently, there is no (easy) way to ensure
that a change in the signature building logic doesn't cause any breaking
changes wrt klibs.
Now, most IdSignatures include hashed mangled names in them, so even if
we catch a regression where the included hash changes, there would be no
way of knowing immediately what caused it, unless we'd also have mangled
names in the expectations.
The reason #2 is to test the manglers themselves. Currently, there are
no tests for them. They heavily duplicate each other, this is already
causing issues (see KT-57427) that would be very hard to catch without
these tests.
^KT-58238 Fixed
The test is not in any way JVM-specific, but it fails on the JS BE
because of different fq-names of stdlib symbols on JVM and JS.
The fix is in progress. Mute the test until the fix is ready.
