[KMTESTS:FSRTL]
Add more failing tests for MCB. These are pretty basics and deal with holes.
They are pretty handy to show how broken the current MCB implementation is, in regard to holes management: it fails at properly counting runs when there are holes and it creates virtual runs (hence the broken count) for each hole. This shouldn't happen.
