[PATCH] D30951: [AArch64] Simplify MacroFusion

Sometimes, the ExitSU is fused twice, since it may be fused once when scanning the successors from the beginning of the BB and the again when scanning the predecessors of ExitSU.

This patch allows an SU from the dependencies list to be specified and to be ignored.  In this case, because its dependencies are scanned at another time.
