QingShan Zhang f8c2a4c0d9 [Scheduling] Create the missing dependency edges for store cluster 
If it is load cluster, we don't need to create the dependency edges(SUb->reg) from SUb to SUa
as they both depend on the base register "reg"

     +-------+
+---->  reg  |
|    +---+---+
|        ^
|        |
|        |
|        |
|    +---+---+
|    |  SUa  |  Load 0(reg)
|    +---+---+
|        ^
|        |
|        |
|    +---+---+
+----+  SUb  |  Load 4(reg)
     +-------+

But if it is store cluster, we need to create it as follow shows to avoid the instruction store
depend on scheduled in-between SUb and SUa.

     +-------+
+---->  reg  |
|    +---+---+
|        ^
|        |         Missing       +-------+
|        | +-------------------->+   y   |
|        | |                     +---+---+
|    +---+-+-+                       ^
|    |  SUa  |  Store x 0(reg)       |
|    +---+---+                       |
|        ^                           |
|        |  +------------------------+
|        |  |
|    +---+--++
+----+  SUb  |  Store y 4(reg)
     +-------+
