Geza Lore a83043d735 DfgPeephole: Rework folding of associative operations

Allow constant folding through adjacent nodes of all associative
operations, for example '((a & 2) & 3)' or '(3 & (2 & a))' can now be
folded into '(a & 2)' and '(2 & a)' respectively. Also improve speed of
making associative expression trees right leaning by using rotation of
the existing vertices whenever instead of allocation of new nodes.
