We can stop using a graph representation of the SLP structure and switch
directly to tree by relying on a single user of each tree node. If the
node has multiple uses, other uses must be represented as a separate
gather/buildvector node, which then will be combined with the existing
vectorized node(s) uoon cost estimation/codegen.
This allow to simplify inner structure and turn in some extra
optimizations, which could not be turned on for the nodes with multi
users (reordering, minbitwidth analysis).
