I fixed the issue with compile time increasing - see usage of MinInstr->getTrace(MBB). Now we're getting the trace when we really need it only. As result the executing profile was totally changed and the compiling time is now even less than it was in DAG Combiner - about 1.5 s on my laptop (I'm speaking about our worst case test only).
