To prevent tests from altering outcomes of the subsequent tests.
Also expose the clearCaches method (in the internal class
ReflectionFactoryImpl) so that it can be used in other places in similar
circumstances
Previously ReflectionTypes.find returned an error class in case a class
is not found in the module dependencies. The problem with this approach
is that each call site should call ErrorUtils.isError on the result and
report an error if needed, in order to stop this type from reaching the
codegen, which can't handle error types.
Now we create a MockClassDescriptor instance instead. It's not an error
class, so it'll be handled correctly in the codegen. Also its scope is
empty and errors are reported on any non-trivial usage (see
MissingDependencyClassChecker), so this approach is not worse than error
classes

Finnaly markers are used only for non-local return processing and are removed after inlining to non-inline functions, same deletion should be performed on inlining to anonymous objects

The problem was that he number of mask parameters for defaults when
generating methods declaration was being calculated upon resulting signature
(with additional parameters: extension receivers, enum name/ordinal),
while on call-sites the masks number was calculated by the arguments number
in resolved call, i.e. by the number of real value parameters.
And because of the additional synthetic parameters (like enum.ordinal) these
two numbers could be different.
The solution is just to use value parameters number in both places.
Note, that we only count value parameters from the original sourse
declaration, ignoring synthetic ones generated by backend (e.g.
Continuation for suspend functions)

See the issue and the test. The problem was that when generating
call to `foo` method in member scope of `AT<*>` its resulting descriptor
after substitution and approximation was: fun foo(x: Nothing..Array<out Nothing>).
This signature is correct, but when using this parameter type
for generating a vararg argument the assertion is violated that
the type of the argument must be an array
(by default we're using lower flexible bound everywhere)
The solution is using upper bound for flexible types that should
always have a form of Array<out T> for varargs (even for such corner cases)
both for Kotlin and Java declarations.
#KT-14607 Fixed
The problem was that LanguageVersionSettingsImpl.DEFAULT did not have
"WarnOnCoroutines" as a feature and so it was manually added to the settings,
but only in two places: in the compiler and in the IDE
