[CodeMoverUtils] Use dominator tree level to decide the direction of
code motion
Summary: Currently isSafeToMoveBefore uses DFS numbering for determining
the relative position of instruction and insert point which is not
always correct. This PR proposes the use of Dominator Tree depth for the
same. If a node is at a higher level than the insert point then it is
safe to say that we want to move in the forward direction.
