Introduce CHECK_TAIL_CALL_OPTIMIZATION directive

Browse Source 
This directive generates TailCallOptimizationChecker in package helpers.
The check for tail call optimization is based on coroutine stack traces
bug (feature?): when tail call optimization hits, the continuation
object is not generated. Thus, there is no debug metadata for this
suspend function. Consequently, the coroutines stack trace does not
contain stack trace element for that function.
This check is performed by TailCallOptimizationChecker.

Since this is runtime check, unlike bytecode tests, it does not require
test data adjustments on each codegen or inliner change.

Since the check is based on debug metadata, which is JVM specific, there
is not support for other backends yet.
