Basically, this commit splits test data from the from java-txt-kt to two pairs java-txt and kt-txt.
This commit leads to some duplication in test data.
This is temporary: in the platform types branch the test data for LoadJava tests will be changed dramatically, so duplication will go away
We do not try to recover too gracefully from a cyclic hierarchy any more:
we simply remove all the edges that belong to a cycle instead of intelligently finding one most convenient edge to cut.
This is done in both lazy and eager resolve to keep tests passing.
