The previous implementation didn't log anything, including stdout,
stderr and the command line, and didn't detect non-zero exit code,
making it hard to investigate the test failures.
With `unitSuspendFunctionObjCExport=proper` binary option,
for Unit-returning suspend functions ObjCExport now generates
completion handlers without redundant `KotlinUnit*` result parameter.
So Swift (5.5+) can import these functions as Void-returning async
functions.

The variable generated by IrStatementBuilder.irTemporary doesn't inherit
startOffset and endOffset from the builder. In particular, as a result,
temporary variables generated for elvis operator left operand have
UNDEFINED_OFFSET.
Additionally, ProvisionalFunctionExpressionLowering copies the offsets
of a variable to lowered lambda in the variable initializer. With the
problem described above, this causes invalid debug information in
Kotlin/Native, see KT-49360.
Fix irTemporary by using builder's offsets for the variable.

Native compiler uses lazy IR for declarations provided by cinterop.
The problem: `FakeOverrideBuilder` requests super types during
type checking, accessing `.owner` for them. So if a type and super type
are represented as lazy IR, and lazy IR generation is not enabled yet,
then the super type symbol won't be bound by this moment, and the access
will fail.
This happens in KT-48816: fake override builder tries to access `.owner`
for `IrClassSymbol` of `NSObject` (super type of `NSDate` and `NSUUID`).
Fix this by enabling lazy IR generation before building fake overrides.
There are number of problems with up-to-date checks in tests, leading to
a test binary not being rebuilt or rerun when a developer expects it to.
Things became worse after updating to Gradle 7+:
test binary run tasks are considered up-to-date if the test data
has been changed, even after clean.
Even before Gradle 7+, we've observed other similar undesirable effects:
for example, if the compiler has been changed, tasks building
test binaries are still up-to-date.
There are quite a lot of different tasks related to running the tests
for Native, many of them are misused and thus don't do what we expect.
Carefully fixing each particular kind seems counterproductive and
unreliable.
So instead workaround all possible similar problems by forcing all tasks
in the :kotlin-native:backend.native:tests project to be not up-to-date.
This project should contain only test tasks, so this workaround
seems pretty natural -- it is just "tests aren't up-to-date".
Unfortunately, llvm removes full debug info from module on any error.
Different version debug info in bitcode is not always compatible, also
it adds this debug info additional requirements on generated debug info.
So this feature is quite unstable and shouldn't be enabled by default,
although it has almost no downsides when worked correctly.
