This option has no effect on the production code. But in a custom
scenario of a local bootstrap, where the compiler is replaced with the
one where JVM IR backend is enabled by default, this option allows to
switch back to the old backend.
All of these arguments (except the one for compiling experimental
coroutines) are supposed to go away as soon as we fix related problems
in the JVM IR backend.
Expression type serves as a part of a key for retrieving smart cast info.
Rewriting expression type with SmartCastManager leads to incorrect processing of following smartcasts for same expression, therefore it was removed.

It's necessary because of new type substitutor is eager than odl, so
if there is a substitution of type parameter deep inside type arguments
then second substitutor wins against first

Since there's no nullability assertion, null could end up in this list
and cause NPE further at `reportNotAcceptedExperimentalities`. This
could happen if a declaration was annotated with WasExperimental, the
marker was annotated with the new RequiresOptIn, and API version 1.2 was
used.
No new tests are added because 1.2 is obsolete and WasExperimental is
internal.
See the test and the issue for the clarification
After the change 7898922066
the expected type for "a" in expression "foo(a)" is A<E & B<*>>
But we have the original type A<E> and smart-casted enriched type A<B<*>>
(non of them is a subtype of A<E & B<*>>)
and fail in checkTypeInternal when checking types in during completion

Treating special functions for `if`, `when`, `try`, `?:` as not accepting `Nothing` result type is incorrect.
Making so leads to cases with uninferred `Nothing` result type for inner calls and lost data flow info.
MissingDependencyClassChecker.collectDiagnostics now show only unique diagnostics
As per-file analyzer trace used in checker delegates to resolve session trace, diagnostics might be duplicated because of race condition:
1. If a non-checker thread performs analyze first, diagnostics for global elements will be stored in the resolve session trace only once.
2 If the checker threads comes to the analyze first, diagnostics will be stored in the local trace, and after that might be duplicated in the resolve session trace by other analyzers.

RequiresOptIn should be used now instead of Experimental, OptIn instead
of UseExperimental. See https://github.com/Kotlin/KEEP/pull/201.
This change adds the new declarations only to the stdlib, and supports
them in the compiler. Because of the way compiler loads annotations, we
need to bootstrap it first before deprecating the old annotations and
updating tests.
#KT-34647 Fixed
Call transformer previously ran completion of argument atoms
only for non-error candidates. This led to missing diagnostics,
i.e. from collection literal resolver.
Now arguments of calls resolved to error descriptor are completed,
with exception to not found provideDelegate calls.
provideDelegate's subatoms are not completed after failure, because
it is a part of delegate competion, which does not end with
unresolved provideDelegate.
Completing after provideDelegate failure removes constraint system
from resolved arguments, which breaks resolve for get/setValue.
