This patch mutes the following test categories: * Tests with java dependencies (System class, java stdlib, jvm-oriented annotations etc). * Coroutines tests. * Reflection tests. * Tests with an inheritance from the standard collections.
Rename/remove some obsolete test cases
Merge tests in boxMultifileClasses/calls to one test case; copy the two resulting tests (+ change box to main) to compileKotlinAgainstKotlin
