Gradle forces non-incremetnal builds,
when a task failed, but its outputs were changed.
This is an issue for Kotlin incremental compilation,
because it also forces all dependent modules to be rebuilt.
This change fixes the issue by reading all output and
restoring it on a compile error/exception.
This change does not affect non-incremental builds.
Simplify ifs when branches have condition true/false.
Simplify blocks containing only a variable declaration
and a variable get of the same variable. Simplify to
just the condition.
Do not introduce temporary variables for constants for
null checks. Constants have no side-effects and can be
reloaded freely instead of going through a local.
This simplifies code such as "42.toLong()!!" so that the
resulting code has no branches and uses no locals. The
simplifications happen as follows:
```
block
temp = 42.toLong()
when
(temp == null) throw NPE
(true) load temp
---> null test simplification
block
temp = 42.toLong()
when
(false) throw NPE
(true) load temp
---> when simplification
block
temp = 42.toLong()
load temp
---> block simplification
42.toLong()
```
consoleView field is initialized in initAndRun inside invokeLaterIfNeeded call.
This may cause NPE in setupGutters if consoleView isn't initialized yet

* if enum class has abstract members, then it is ABSTRACT
* otherwise, if enum class has entries with members, then it is OPEN
* otherwise, it is FINAL.
In case of the same class defined in different modules they contain
different descriptors instances in their scope that might lead
to failing assertion in findConcreteSuperDeclaration
because there are overridden from different modules
It might happen even in the compiler because of different built-in modules
defined for sources-module and for dependencies' one
^KT-29320 Fixed
On windows using a project's root
as a working directory for the daemon
seems to prevent removing the directory
when the daemon runs.
Different projects may share an instance of the daemon,
so the issue will be present only in a project
which started the daemon.
In super class constructor arguments, 'this' can be resolved
as a reference to a companion object of a superclass.
This breaks an assumption in psi2ir that 'this' can only refer to some
receiver from the current scope.
If 'this' refers to an 'object' (including 'companion obejct'),
and we are not inside the corresponding class scope,
then 'this' represents a reference to a singleton instance "by name"
(represented as IrGetObjectValue).
Introduce lowering to remove null checks for primitive type
expressions and replace them with true/false. Side-effects
are preserved.
Generate ifnull/ifnonnull instructions for null checks instead
of materializing a null literal for an equality check.
