Cleanup of likelyFailLow logic This patch broadens and simplifies definition of PvNode that is likely to fail low. New definition can be described as following "If node was already researched at depth >= current depth and failed low there" which is more logical than the previous version and takes less space + allows to not recompute it every time during move loop.
