mtrofin 78b55f2ebc If all the predecessors of a node have, at the last gap, the exact same 
moves, we move those to the node, and remove them from the
predecessors ("merge" them to the common node).

If only some of the moves are common, we don't do anything. This is
what this change addresses.

The bug linked below should be addressed by this change. The only
difference in codegen before/after the change that introduced the bug
was un-merged moves.
