The problem was that when obtaining char from the wrapper,
codegen used int as expected type that led
to a ClassCastException: java.lang.Character cannot be cast to java.lang.Number
The solution is using coercion to chars, it's still correct,
because of implicit widening coercion in JVM from C to I

LanguageVersionSettings can be read from the configuration. Also, the
configuration may be used for other stuff, not related to language version
settings, soon
The main problem here is that moduleName that is being passed to KPackageImpl
is useless: as can be seen in
ClosureCodegen.generateCallableReferenceDeclarationContainer, the name of the
current module is always written to the class file for a callable reference,
not the name of the module of the referenced declaration. This resulted in
reflection not loading the correct .kotlin_module file and subsequently not
finding the required file facade for a top-level function.
The commit does not fix the issue with the incorrect module name written in the
back-end, but workarounds it. It turns out, reflection can figure out the name
of the module of the referenced declaration itself by parsing the header from
the given java.lang.Class object for a single-file/multi-file package facade
and extract the package_module_name protobuf extension. Similar code was
already there in Member.getKPackage() in ReflectJvmMapping.kt but it did not
support multi-file classes, of which there are a lot in the standard library;
this is now supported

Do not wrap initial continuation for startCoroutine in SafeContinuation
This changes leaves only internal declarations and intrinsics as platform
dependent parts of the coroutine library, the rest parts (public API)
is implemented through them in common module
- Split CoroutinesLibrary into common and JVM parts
- Get rid of startCoroutine duplications
- Make suspendCoroutine implementation to be platform independent
Previous version of the boxing/unboxing analysis treated merging boxed and non-boxed values as a hazard.
If such merged values are not used (e.g., early return + local variables reused in inlined calls),
corresponding boxing/unboxing operations still can be optimized out.
All information related to boxed value usage by instructions is moved to 'BoxedValueDescriptor'.
Introduce "tainted" (and "clean") boxed values, with the following rules:
merge(B, B) = B, if unboxed types are compatible,
T, otherwise
merge(B, X) = T
merge(T, X) = T
where
X is a non-boxed value,
B is a "clean" boxed value,
T is a "tainted" boxed value.
Postpone decision about value merge hazards until a "tainted" value is used.
