Add synthesize uses at back edge. This reduces the cost of linearizing the graph (hence removing the notion of back edge). Since linear scan allocates/spills registers based on next use, adding a use at a back edge ensures we do count for loop uses. Change-Id: Idaa882cb120edbdd08ca6bff142d326a8245bd14
